GEODE-2900: push shadow key back into the front of the eventSeqNumber
"Queue"

>
> In this scenario when peek() is called from BucketRegionQueue, a side effect
> is that the key is removed from the eventSeqNumQueue and an event is placed
> into the peekedEvents list.
> If there is failure dispatching the event, we add the peekedEvents list to a
> new peekedEvents list. Before doing so, we remove any events that we are not
> primary for. Now the event is not in the eventSeqNumQueue or the
> peekedEvents list
> If we now become primary (before the other node could dispatch this event),
> and because we do not have that event in the eventSeqNumQueue or the
> peekedEvents, it gets "stuck."
