Test that, when a parallel gateway sender is added to a partitioned region through attributes
mutator, transaction events are not sent to all region members but only to those who are
hosting the bucket for the event and thus, events are not stored in the bucketToTempQueueMap
member of the ParallelGatewaySenderQueue.
No redundancy in the partitioned region.
