In the `integration_test` CircleCI job, we run `yarn install` on all projects in the `integration/` directory. If a project has no lockfile or if the lockfile is out-of-sync with the corresponding `package.json` file, then the installed dependency versions are no longer pinned, which can result in different versions being installed between different runs of the same job (if, for example, a new version is released for a package) and breaks hermeticity. This could be prevented by using the `--frozen-lockfile` option with `yarn install`, but this is not possible with the current setup, because yarn needs to be able to install the locally built Angular packages, whose checksums will be different from the ones in the lockfile. Therefore, we have to manually ensure that the lockfiles remain in-sync with the corresponding `package.json` files for the rest of the dependencies. For example, previously, [cli-hello-world-lazy/yarn.lock][1] had an entry for `@angular-devkit/build-angular@0.900.0-next.9` (pinned to `0.900.0-next.9`), but [cli-hello-world-lazy/package.json][2] specified the `@angular-devkit/build-angular` version as `^0.900.0-rc.0` (note the leading caret). As a result, since the version in the lock file does not much the one in `package.json`, the lockfile is ignored and the latest available version that matches `^0.900.0-rc.0` is installed. This, for example, started causing unrelated CI failures ([example][3]), when `@angular-devkit/build-angular@9.0.0-rc.3` was released with a size improvement. This commit ensures that all integration projects have a lockfile and that lockfiles are up-to-date (with the current `package.json` files).
