Improve tests to use output surfaces more realistically 

Prior to this change, there were some unrealistic quirks in
our Robolectric tests. For example, onRenderedFirstFrame would
be called when using FakeVideoRenderer, despite no output to
render the frame to ever being set. This change improves the
realism of these tests. These changes are required for some
improvements being made to how outputs are set on video
renderers.
