Subject: [PATCH] fix: fix emitting of events received during connection
 establishment (#695)

Previously, the event name of packets received during the connection
handshake would not be removed from the arguments array:

```java
socket.on("my-event", new Emitter.Listener() {
    @Override
    public void call(Object... args) {
        System.out.println(Arrays.toString(args)); // prints ["my-event", "arg1", "arg2", "arg3"]
    }
});
```
