    Correctly give focus to the user chooser on startup
    
    We manually handle how focus works in the GdmChooserWidget container,
    and we try to automatically move the focus to the treeview inside the
    chooser. However, it fails the first time because the treeview is not
    realized yet and the logic in the code assumes that if focus moved to
    the chooser, it moved to the treeview, so later attempt to get the focus
    grabbed by the treeview are just ignored.
    
    It works fine when using gtk_widget_child_focus() to give the focus to
    the treeview. And this makes more sense since the chooser is a container
    anyway.
