    playlistcontrols: Fix playlist deletion
    
    CoreModel used to have a property named active_playlist to keep track
    of the playlist being played. This property has been superseded by the
    active_core_object property which keeps track of the object being
    played (playlist, artist, song or album). However, the delete_action
    from PlaylistCreation was not updated to use active_core_object. This
    results in a crash when a playlist is deleted.
    
    This issue is fixed by replacing active_playlist with
    active_core_object.
