    artistalbumwidget: Correctly set discbox properties
    
    If the model has already been loaded (if the artist has already been
    selected from ArtistsView), _on_model_items_changed method will never
    be called. Therefore, the properties associated with each
    DiscBox (selectable and show_disc_label) will not be set correctly.
    
    Fix the issue by manually calling items_changed in the constructor.
    
    Closes: #300
