Try to fix autoplay with ios/safari

* Disable autoplay on first load because we have weird issues (player
 starts to play and stop so we loose the big play button). We also don't
 want to autoplay muted videos (bad UX IMHO and we don't have ads to
 display)
 * Enable autoplay when we already played a video (fixes the issue with
 playlists)
