Reland "Always use real VideoStreamsFactory in full stack tests"

Reland with fixes. Previous iteration affected media bitrate in bunch of tests.

Always use real VideoStreamsFactory in full stack tests

Because quality scaling is enabled now in full stack test, correct
factory should be used to compute actual resolution.

Also, since analyzed stream may be disabled completely now, change how
analyzer considers the test finished --- count captured frames and
stop if required amount of frames is captured and no new comparison were made.
