[Cosimo Cecchi <cosimoc src gnome org>]

commit a98c9300f4f6eedba8f6a54411e682107f259eda
Author: Florian Müllner <fmuellner gnome org>

    Remove libnotify dependency
    
    After the port to GNotifications, libnotify is only used to check
    whether the server supports persistence. Just call the underlying
    DBus method directly and remove the dependency.
