[caribou: 21/23] Use async Bus.get_proxy()

[Eitan Isaacson <eitani src gnome org>]

commit aae4d8f894f253b1f5d5b1da540502437c37c0ec

    Use async Bus.get_proxy()
    
    The sync version of this method would result in apps hanging
    briefly at startup, however in the async version a window may be
    created/focused before the async callback runs.
