When `ng add` is invoked independently of `ng new`, a node installation
of `@angular/bazel` is performed by the CLI before invoking the
schematic. This step appends `@angular/bazel` to the `dependencies`
section of `package.json`. The schematics then appends the same package
to `devDependencies`.
This leads to the warning:
```
warning package.json: "dependencies" has dependency "@angular/bazel" with
range "^8.0.0-beta.13" that collides with a dependency in "devDependencies"
of the same name with version "~8.0.0-beta.12"
```
