      Description

      When resource localization fails [Public localizer / LocalizerRunner(Private)] it sends ContainerResourceFailedEvent to the containers which then sends ResourceReleaseEvent to the failed resource. In the end when LocalizedResource's ref count drops to 0 its state is changed from DOWNLOADING to INIT.
      Now if a Resource gets ResourceRequestEvent in between ContainerResourceFailedEvent and last ResourceReleaseEvent then for that resource ref count will not drop to 0 and the container which sent the ResourceRequestEvent will keep waiting.
