    view-model: Always notify selection changes
    
    Sometimes selection changes are not notified, which causes regressions:
    
      * `nautilus --select /path/to/file` fails to select file
      * going to parent folder fails to select child folder we came from
    
    As we implement GtkSelectionModel ourselves, we can and should notify
    these changes even if the internal GtkMultiSelection doesn't.
