    GjsDBusImplementation: unref the invocation passed to method_call()
    
    In C code, the reference passed to the method_call() virtual function
    would be passed to the return_value/error function that is eventually
    called. But since these functions are called from JS, and the calling
    convention is normalized, we need to unref reference passed to
    method_call ourselves. See GLib bug 738259 for a more complete discussion.
