Reproduce this problem:
1. Container was running and ContainerManagerImpl#localize was called for this container
2. Localization failed in ResourceLocalizationService$LocalizerRunner#run and sent out ContainerResourceFailedEvent
with null LocalResourceRequest.
3. NPE when ResourceLocalizationFailedWhileRunningTransition#transition --> container.resourceSet.resourceLocalizationFailed(null)

I think we can fix this problem through ensuring that request is not null before remove it.
