ff741f6a96 Ensure deletion of pods in queues and cache 
When the client misses a delete event from the watcher, it will use the last state of the pod in the informer cache to produce a delete event. At that point, it's not clear if the pod was in the queues or the cache, so we should issue a deletion in both.

The pod could be assumed, so deletion of assumed pods from the cache should work.
