Worker model's "queue_name" property returns the wrong name on Celery 4.x
CLOSED - CURRENTRELEASE
Returns <name>.dq instead of <name>.dq2 as would be correct

The queue suffix is dependent on celery version. Celery 4 uses ".dq2" so we need to handle that case when we recreate the queue name as part of the detail view.
