触摸事件回调的js对象错了

ScriptingCore::getInstance()->handleTouchesEvent(ret, EventTouch::EventCode::MOVED, touches, event); 
ret 是EventListenerTouchAllAtOnce实例，而不是Node的实例，在js的function 中 (this)所指的是EventListenerTouchAllAtOnce实例
@lihaibo1989 As you said, here we want to pass the touch event listener itself, so ret is correct. If you pass the associatedNode, then it will become the context of `onTouchesBegan` function which is not the correct behavior
