Keep pending initial position when setting empty playlist

Browse Source 
MediaControllerImplBase currently drops the pending initial seek
position when a user sets an empty playlist.

When seeking in empty playlists and setting new empty playlists,
the class also drops the the period index (and wrongly assigns zero
instead of the windowIndex).
