    albumwidget: Bind ListModel early
    
    If we start listening to ListModel items-changed signals before binding
    the model to the ListBox, it might not yet be synced and crash in the
    signal callback. The callback assumes the ListBox widgets are already
    created and this might result in a crash.
    
    Bind the ListBox widget before connecting the signal handler.
    
    Closes: #367
