test(bazel): fix bazel-workspace schematics test

The test was cherry-picked from #27719 into 7.1.x, where entry module
path ended in `/main`, not `/main.dev`. It was changed to `/main.dev`
in #27277, which was not backported to 7.1.x.

+# BuildKite configuration
+
+This folder contains configuration for the [BuildKite](https://buildkite.com) based CI checks for 
+this repository.
+
+BuildKite is a CI provider that provides build coordination and reports while we provide the 
+infrastructure.
+
+CI runs are triggered by new PRs and will show up on the GitHub checks interface, along with the 
+other current CI solutions.
+
+Currently it is only used for tests on Windows platforms.
+
+
+## The build pipeline
+
+BuildKite uses a pipeline for each repository. The `pipeline.yml` file defines pipeline 
+[build steps](https://buildkite.com/docs/pipelines/defining-steps) for this repository.
+
+Run results can be seen in the GitHub checks interface and in the 
+[pipeline dashboard](https://buildkite.com/angular/angular).
+
+Although most configuration is done via `pipeline.yml`, some options are only available
+in the online [pipeline settings](https://buildkite.com/angular/angular/settings).
+
+
+## Infrastructure
+
+BuildKite does not provide the host machines where the builds runs, providing instead the
+[BuildKite Agent](https://buildkite.com/docs/agent/v3) that should be run our own infrastructure.
+
+
+### Agents
+
+This agent polls the BuildKite API for builds, runs them, and reports back the results.
+Agents are the unit of concurrency: each agent can run one build at any given time. 
+Adding agents allows more builds to be ran at the same time.
+
+Individual agents can have tags, and pipeline steps can target only agents with certain tags via the
+`agents` field in `pipeline.yml`.
+For example: agents on Windows machines are tagged as `windows`, and the Windows specific build 
+steps list `windows: true` in their `agents` field.
+
+You can see the current agent pool, along with their tags, in the 
+[agents list](https://buildkite.com/organizations/angular/agents).
+
+
+### Our host machines
+
+We use [Google Cloud](https://cloud.google.com/) as our cloud provider, under the 
+[Angular project](https://console.cloud.google.com/home/dashboard?project=internal-200822).
+To access this project you need need to be logged in with a Google account that's a member of 
+team@angular.io. 
+For googlers this may be your google.com account, for others it is an angular.io account.
+
+In this project we have a number of Windows VMs running, each of them with several agents.
+The `provision-windows-buildkite.ps1` file contains instructions on how to create new host VMs that
+are fully configured to run the BuildKite agents as services.
+
+Our pipeline uses [docker-buildkite-plugin](https://github.com/buildkite-plugins/docker-buildkite-plugin)
+to run build steps inside docker containers.
+This way we achieve isolation and hermeticity.
+
+The `Dockerfile` file describes a custom Docker image that includes NodeJs, Yarn, and the Bazel 
+pre-requisites on Windows.
+
+To upload a new version of the docker image, follow any build instructions in `Dockerfile` and then
+run `docker build -t angular/node-bazel-windows:NEW_VERSION`, followed by 
+`docker push angular/node-bazel-windows:NEW_VERSION`. 
+After being pushed it should be available online, and you can use the new version in `pipeline.yml`.
+
+
+## Caretaker 
+
+BuildKite status can be found at https://www.buildkitestatus.com/.
+
+Issues related to the BuildKite setup should be escalated to the Tools Team via the current 
+caretaker, followed by Alex Eagle and Filipe Silva.
+
+Support requests should be submitted via email to support@buildkite.com and cc Igor, Misko, Alex,
+Jeremy and Manu
+
+
+## Rollout strategy
+
+At the moment our BuildKite CI uses 1 host VM running 4 agents, thus being capable of 4 concurrent 
+builds.
+The only test running is `bazel test //tools/ts-api-guardian:all`, and the PR check is not 
+mandatory.
+
+In the future we should add cache support to speed up the initial `yarn` install, and also Bazel
+remote caching to speed up Bazel builds.
+
+After the current setup is verified as stable and reliable the GitHub PR check can become mandatory.
+
+The tests ran should also be expanded to cover most, if not all, of the Bazel tests.

+# Encryption
+
+Based on https://github.com/circleci/encrypted-files
+
+In the CircleCI web UI, we have a secret variable called `KEY`
+https://circleci.com/gh/angular/angular/edit#env-vars
+which is only exposed to non-fork builds
+(see "Pass secrets to builds from forked pull requests" under
+https://circleci.com/gh/angular/angular/edit#advanced-settings)
+
+We use this as a symmetric AES encryption key to encrypt tokens like
+a GitHub token that enables publishing snapshots.
+
+To create the github_token file, we take this approach:
+- Find the angular-builds:token in http://valentine
+- Go inside the CircleCI default docker image so you use the same version of openssl as we will at runtime: `docker run --rm -it circleci/node:10.12`
+- echo "https://[token]:@github.com" > credentials
+- openssl aes-256-cbc -e -in credentials -out .circleci/github_token -k $KEY
+- If needed, base64-encode the result so you can copy-paste it out of docker: `base64 github_token`

+## Developing on Windows
+The `packages/` directory may contain Linux-specific symlinks, which are not recognized by Windows.
+These unresolved links cause the docs generation process to fail because it cannot locate certain files.
+
+> Hint: The following steps require administration rights or [Windows Developer Mode](https://docs.microsoft.com/en-us/windows/uwp/get-started/enable-your-device-for-development) enabled!
+
+To fix this problem, run `scripts/windows/create-symlinks.sh`. This command creates temporary files where the symlinks used to be. Make sure not to commit those files with your documentation changes.
+When you are done making and testing your documentation changes, you can restore the original symlinks and delete the temporary files by running `scripts/windows/remove-symlinks.sh`.
+
+It's necessary to remove the temporary files, because otherwise they're displayed as local changes in your git working copy and certain operations are blocked.
 
 ## Using ServiceWorker locally
 
-Since abb36e3cb, running `yarn start --prod` will no longer set up the ServiceWorker, which
-would require manually running `yarn sw-manifest` and `yarn sw-copy` (something that is not possible
-with webpack serving the files from memory).
-
-If you want to test ServiceWorker locally, you can use `yarn build` and serve the files in `dist/`
-with `yarn http-server dist -p 4200`.
-
-For more details see #16745.
+Running `yarn start` (even when explicitly targeting production mode) does not set up the
+ServiceWorker. If you want to test the ServiceWorker locally, you can use `yarn build` and then
+serve the files in `dist/` with `yarn http-server dist -p 4200`.
