rpc cannot work with worker thread

[liuluheng]

test code

NPL.load("(gl)script/ide/System/Concurrent/rpc.lua");
local rpc = commonlib.gettable("System.Concurrent.Async.rpc");
rpc:new():init("Test.testRPC", function(self, msg) 
	LOG.std(nil, "info", "category", msg);
	msg.output=true; 
	ParaEngine.Sleep(1);
	return msg; 
end)

-- or not
Test.testRPC:MakePublic();

-- test with worker thread
Test.testRPC("(worker1)", {"input"}, function(err, msg) 
    echo(msg)
end);
