test(@angular/cli): allow invalid deps E2E to pass on release commits

When installing an outdated version of `@schematics/angular`, the package manager will also analyze installed dependencies.  In the case of a release commit those dependencies are not yet on the npm registry and the outdated package install will fail. To remedy this situation, the outdated package and its two dependencies are published to the local test registry which allows the unreleased versions of the tooling packages to also be available to the package manager.

(cherry picked from commit 3806903)
