Title: Update SocketIO.java

public String getHeader had logic error !

```
public String getHeader(String key) {
if (this.headers.contains(key)) // headers.contains(param) - get true if map
//has param value. this method do not check KEYs in container !
return this.headers.getProperty(key);
return null;
}
```

I update it like this :
```
if (headers != null)
return this.headers.getProperty(key);
```
