[gnome-music/wip/jfelder/selection-misc-cleanups: 4/7] albumwidget: Do not bypass DiscListBox on selection-mode changes

    albumwidget: Do not bypass DiscListBox on selection-mode changes
    
    There is a direct binding between the AlbumWidget and each DiscBox. It
    means that DiscListBox selection-mode never changes.
    
    Fix the issue by replacing this binding by two bindings:
    * one between the AlbumWidget and the DiscListBox
    * one between the DiscListBox and each DiscBox
