ci: update components repo unit tests job commit

Updates the commit the `components-repo-unit-tests` job runs
against. The goal is that we run against a revision that at
least contains: angular/components#19273.

The new commit contains fixes for a flaky test in the datepicker that we
saw failing in the components-repo-unit-tests job too:
