Updates the `material-unit-test` job to run tests against
the latest commit of the Angular Components repository.

The components repository updated to rules_nodejs#0.38.2 before Angular Bazel did.
To do this, the `@angular/bazel` v0.38.2 compatibility changes were patched on postinstall.

This now conflicts because we install a `@angular/bazel` version in the `material-unit-tests` job
that already includes these compatibility changes. This would result in the patch being a noop
for which the `patch` command throws an error.

We can remove this once components can install a released version of `@angular/bazel` that is
compatible with `rules_nodejs#0.38.2`.
