Find out why a relay in previous consensuses is not found

Talking with @gk by IRC we had the case of a relay not being found by margot by nickname that instead appeared in metrics.tpo (does it has 2h delay) and consensus-health.tpo.

It might be the case that the relay just went offline or changed name and margot couldn't find it cause looking at a more recent live consensus.

I couldn't find the relay either in the local arti storage.
