    selectionbar: Setup UI once window is constructed
    
    This is part of the move of the 'selection-mode' property from App to
    AppWindow. This adds setup_ui() to the Selectionbar class to ensure that
    the connection to the notification of 'selection-mode' is done once the
    window is constructed.
    
    This is needed to drop the use of AppWindow singleton and therefore to
    make multiple windows possible.
