Break early when delete happens in outdated state
A panic could happen when multiple delete messages are sent one after
another without waiting until there are no messages left to be deleted:
panic: runtime error: makeslice: len out of range
goroutine 1 [running]:

The make that blows up is:
uids := make([]uint32, len(store.uids)-len(msg.Uids))
This change simply checks whether the make is going to be valid before
starting to work on the actual delete. If there are more messages queued
to be deleted than what's left in the store, then we're obviously in an
inconsistent state, ask for an update and break.
