[gnome-music/wip/jfelder/selection-coresong-playlist] grltrackerplaylists: Do not bind selected property

    grltrackerplaylists: Do not bind selected property
    
    This results in a wrong selection count because the same song is added
    two times to the selected_items list of CoreSelection.
    
    Besides, the songs of a playlist can not be selected. So, it is
    pointless to bind this property.
    
    Closes: #379
