Updates the commit that the `components-repo-unit-tests` job runs
against to the latest available commit at time of writing.

The motivation for updating is that a lot of changes have been made, and
that a upcoming framework PR that fixes check no changes for OnPush
components exposed a test failure in `angular/components`.
