tonihei 4289708323 Fix DefaultAudioSinkTest flakiness.
Some calls to handleBuffer return false while a previous
flush is still handled in the background.

Fix this by either asserting the method returns true if
we don't expect any delay, or calling it repeatedly until
it returns true (within a timeout).
