Bug 1219711 - Let fake stream take precedence in testing. r=jib TL;DR requesting a fake stream always gives you a fake stream. No magic. The gUMConstraint `fake: true` should take precedence and if set always use MediaEngineDefault. If it is set the state of `faketracks` is passed on to MediaEngineDefault. If it is not set, but (any of) audio/video loopback devices are set, the device enumeration will filter out only those.
