Subject: [PATCH] Skip failing FBF tests in Google Chrome when running
 `makeref` on the bots

Note that this will still allow the FBF tests to run locally, and also on the bots when invoked with `test`/`browsertest` (to not lose all the FBF test-coverage), but will no longer prevent `makeref` from running successfully on the bots.
