When the GII was going, some of BatchRemoval messages (especially for events destroyed due to
conflation) might have failed since the event might not be found in the BucketRegionQueue.
Those messages are added to failedBatchRemovalMessageKeys map in ParallelQueueRemovalMessage.
Events found in the map need to be destroyed once GII is done. Fix for #47431. This method is
invoked deliberately after this.initialized is set to true to fix defect #50316.
