Cocos2dx-lua集成后未能在AirtestIDE上显示控件树

**描述问题bug**

集成poco之后，在AirtestIDE上不现实控件树

**复现步骤**

1、集成poco到App
2、打开App（显示服务启动成功：[LUA-print] [poco] server listens on tcp://*:15004）
3、AirtestIDE选择cocos-lua刷新控件树：[LUA-print] [poco] new client accepted 127.0.0.1 nil

**预期效果**
AirtestIDE显示控件树

**相关截图**
1、通过添加日志：发现能够正确的接手到dump请求：
[LUA-print] [poco] onRequest table: 0xc90cd120 Dump table: 0xc90cd3e0
2、在client返回前打印返回信息，结构如下
```
