Calling a method of a class from onClose() does not actually call the method
Ex:
```php
public function onClose(ConnectionInterface $conn)
  {
    // The connection is closed, remove it, as we can no longer send it messages
    SQSManager::sendLog($clientMessage);
    $this->clients->detach($conn);
  }
```
This sendLog() method never gets called.

Am I missing anything?
I tried the non-static way too.
