* Fix `onPositionDiscontinuity` event so that it is not triggered with
reason `DISCONTINUITY_REASON_PERIOD_TRANSITION` after a seek to another
media item and so that it is not triggered after a timeline change.
* Trigger `onMediaItemTransition` event for all reasons except
`MEDIA_ITEM_TRANSITION_REASON_REPEAT`.
