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.
