able to change Query for reconnect

just leave a simple access to socket object to able to change query for auto-reconnection

```
var wrappedSocket = {
on: addListener,
socket:socket, //this line
addListener: addListener,
once: addOnceListener,
...
```

example of using

```
this.socket.socket.socket.options.query = '?token='+user_token;
```
