[gnome-music/wip/mschraal/core] player: Rename PlayerPlaylist index to position

[Marinus Schraal <mschraal src gnome org>]

commit c01d807db8e03b69218b8cf9ae02c628264846ff

    player: Rename PlayerPlaylist index to position
    
    Position fits better.
    
    This currently clashes a bit with Player get/set_position, need to consider
    this at some later point.
