Celery queue names inconsistent

[PrivacyDragon]

Is your feature request related to a problem? Please describe.
In the admin interface, the Celery Status tab shows all the current queues.
They seemed to be only ever-increasing recently, so I had to look into why that happened.
After a lot of wasting of time, I figured out how to properly get into Flower, (and how to start it...)
Here, I discovered that the Celery worker was ignoring all but four of the queues, so I had to manually add them.
This did not really seem to be a problem. However, when I entered broadcasts, as that is what the queue is named in the admin interface, nothing happened. An investigation later I found out that the queue was actually called broadcast, singular.

Describe the solution you'd like
So, please fix that. Either change the name of the queue, or change it in the admin interface, so that someone can look at the admin interface to know what the queue names are...
