fixes a bug where bufferingState is in delayed, but gets set back to .ready even though isPlaybackLikelyToKeepUp is false.  Only change the state to .ready if the item is likely to keep up.  Not changing state to .delayed in an else block here since the player might still have some buffer left even though it may not keep up as this could change with bandwidth
