    libgdm: use g_object_unref instead of g_clear_object for weakrefs
    
    At the moment we add a weakref on each proxy to the connection
    object.  For the _sync variant functions, When the weakref fires,
    they call g_clear_object, clearing the connection, even if other
    proxies still have a reference.
    
    This commit changes that weak ref code to use g_object_unref instead.
