I think this should be fixed by:
I have asked a review from @vinothkannans as he worked on this. I feel like the spec here should be reworked, we currently randomly test on few types, but we should have a context for each type which would test create/update/delete.
What was happening here, is that we were requiring a duration for delete_replies type even when removing it, when we actually rely on the fact that duration is nil to remove the timer.
