    artistalbumswidget: Route selections via coreobjects
    
    Selection changes were triggered through the widgets. However,
    this is rather the long way around if you want to actually select
    the coreobjects. Also, in GTK4 it is frowned upon cycling through
    widgets to obtain their properties.
    
    Trigger selection changes directly through the coreobjects.
