Description

IGNITE-11406 has not been fixed properly for two reasons. The first is one is that GridCacheProcessor.utilityCache could be accessed before the first exchange finished. The second is that it doesn't resolve the original issue, because GridServiceProcessor.onKernelStop is followed by GridCacheProcessor.onKernelStop, so caches should be already initialized. Thus that fix should be reverted.

Revering this fix induces the issue related to accessing the utility cache by getting cluster name.
