35cdbdf669 Remove check causing informers to miss notifications
Fix DeltaFIFO bug that caused the sync delta created by a relist
for object ID X to be dropped if the DeltaFIFO already stored a
Delete delta for X. This caused SharedIndexInformer to miss create
notifications. Also, add unit test to expose the bug.
