QA: Add a test that does not run in the build yet.

Merge this in order to pick up the fix from the Nearby
work that causes tests with more than one scenario
to have no profile past the first scenario, and
prevents launching Chrome

This test has no target environment, no steps file yet,
and no pages created.  It is a no-op, but without the
Nearby fix it is difficult to run locally
