Do Not Update Validator Registry on Nil Block #2326

No tracking issue. We had a problem where we would attempt to update the validator registry and request a mutex lock many times if many validators were requesting assignments through a skip slot. We prevent this from happening by not allowing the registry to be updated if there is a nil block.
