Fix for issue #1172
Created by: dsparacio
Rep switch caused data to update and eventually triggered startAutoPlay check. This would not happen with audio /video if paused unless schedulewhilepause was true and ABR switch occurred while paused, unlikely but possible. Fragment Text on the other hand, controlled by UI, can cause a rep update while paused so we prevent this if not the initialPlayback. Will fix A/V edgecase as well.
