Revert 5711 "Fixing a flaky test in video_engine_tests"

Browse Source 
> Fixing a flaky test in video_engine_tests
> 
> VideoSendStreamTest.SuspendBelowMinBitrate was flaky. The problem was that when the first non-padding packet was sent after the stream was resumed, the statistics had not always been updated so that stats.suspended was false. After seeing the first non-padding packet after suspension, the test will now go into a state where it waits for the statistics to be changed.
