Ninjabot instance has no attribute 'message_queue'

While starting sometimes an exception is raised:

ninjabot-allmywut git:master ❯ python ninjabot.py                                                                  ✹ ✭

During handling of the above exception, another exception occurred:

I'm gonna laugh if this is another race condition.
