Use ExoPlaybackException.MediaPeriodId in prewarming error handling

Browse Source 
With using the `MediaPeriodId` from the `ExoPlaybackException`, ExoPlayerImplInternal can set the same id to the renderer group(primary and secondary).

Tested with `ExoPlayerWithPrewarmingRenderersTest` error-based unit tests like `play_errorByPrewarmingSecondaryRendererAfterAdvancingReadingPeriod_doesNotResetPrimaryRenderer`. If the media period was not set in BaseRenderer then the exception would have the incorrect mediaperiod, attribute the error to the non-prewarming renderer, and the test would fail.
