    gdbus: Don't use g_assert_no_error() GDBusObjectManagerServer
    
    There are real world cases where emitting signals can fail, such
    as if the DBus connection closes. Asserting and aborting the process
    in these cases is just plain lazy.
    
    Ignore the errors when the connection is closed, and turn the
    others into warnings.
