    switcherPopup: Bind to the stage, not the monitor
    
    The switcher popup is a large, mostly transparent actor that
    should cover all the clickable area of GNOME Shell. In Clutter
    terms, it should cover the whole stage.
    
    By binding it to the primary monitor, the Alt+Tab behavior
    becomes a bit inconsistent. For example, by not hiding when
    clicking at empty spaces at other monitors.
    
    Fix that by binding the SwitcherPopup to the whole stage,
    and not only the primary monitor.
    
    Fixes https://gitlab.gnome.org/GNOME/gnome-shell/issues/647
