On master failover we have to resent all the shard failed messages, but the transport requests remain the same in the eyes of `equals`. If the master failover is registered and the requests to the new master are sent before all the callbacks have executed and the request to the old master removed from the deduplicator then the requuests to the new master will incorrectly fail and the snapshot get stuck. Closes elastic#51253
