andrewlewis c361e3abc3 Fix handling of delayed AdsLoader.start ... AdsMediaSource posts AdsLoader.start to the main thread during preparation, but the app may call AdsLoader.setPlayer(null) before it actually runs (e.g., if initializing then quickly backgrounding the player). This is valid usage of the API so handle this case instead of asserting. Because not calling setPlayer at all is a pitfall of the API, track whether setPlayer has been called and still assert that in AdsLoader.start.
