Enhance extension UI testing by enabling you to select which extension

APIs to forward (and thus stub out in your test), while others will
keep being fulfilled as per usual.  This lets you build tests that
stub out one piece of behavior while testing that some side effects of
another API happen as expected.

BUG=none
