    gdbus: Flush the async metadata calls
    
    Otherwise it would not be guaranteed that the messages got actually
    sent if a program exits afterwards.
    
    Synchronously flushing queued messages on a shared GDBusConnection
    is quite risky as the queue could be rather long and we would block,
    however the affected calls are not that common in normal use.
