    app-window: Don't bind a11-name to topbar.status
    
    Permanently binding 'accessible-name' property to topbar.status could
    easily lead to null be set on this non-nullable property and that leads
    to warnings on the console from gtk+. We only need machine's name set as
    'accessible-name' when machine in question is in the foreground, so no
    need for this binding anyway.
