Description

In pre-Zab1.0, we would process the NEWLEADER packet in registerWithLeader. Now we only process it in syncWithLeader, and in certain circumstances (the first follower of a new leader) it seems like we get 2 of them, which causes 2 snapshots to be taken one right after another. Not sure whether we should ignore taking the snapshot the second time, or not send two packets, or what.
