Step to reproduce:
- make some viewChanges
- demote node1 with current viewNo X
- Simultaneously stop indy-node on all nodes (exclude demoted node)
- Simultaneously start indy-node on all nodes (exclude demoted node)
- Promote node1
node1 cannot link with any viewChange from pool, until it reach #(X+1) (more than current viewChange on node1).
Re-promoted node accept viewNo from other nodes
