    artistsview: 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.
