olly c7b3fa367b HLS: Fix issue where a live event doesn't transition to STATE_ENDED
The problem occurs when the primary media playlist URL switches
from one whose latest snapshot has not yet got the ended tag, to
one whose latest snapshot already has the ended tag. In this case:

- We trigger a redundant load of the ended playlist.
- When the redundant load completes,
  MediaPlaylistBundle.processLoadedPlaylist detects that the
  playlist is unchanged from the one it already has, and so
  doesn't call onPlaylistUpdated.
- PrimaryPlaylistListener.onPrimaryPlaylistRefreshed is never
  called with the new primary. Hence the externally visible primary
  is still the one that hasn't ended. HlsMediaSource therefore thinks
  the event hasn't ended, which in turn prevents the player from
  transitioning to the ended state.

This commit detects when the new primary already has the ended tag.
In this case, we call onPrimaryPlaylistRefreshed directly and remove
the unnecessary playlist load.
