Fix clearing of candidates from previous iterations

During initialization the CandidateRegistry wasnt clearing
candidates from the previous instance in a reliable way.
Event with ReadMajority if the cluster members havent been updated
yet, it acted as if there were no candidates present so it did
not clear them.

Introduce a mechansim that goes through the akka singleton that
picks owners, so it only executes the clearing of candidates once
the cluster is in a healthy state.
