impossible to rebalance cluster when one node was failover before offline upgrade 2.0.0->2.0.1 cluster(cluster is broken, pun on the UI)

test: newupgradetests.MultiNodesUpgradeTests.offline_cluster_upgrade,initial_version=2.0.0-1978-rel,nodes_init=2,during-ops=failover,upgrade_version=2.0.1-112-rel,initial_vbuckets=64

steps:
1. 2.0.0 release cluster with 2 nodes 10.3.121.112 & 10.3.121.113(2.0.0-1978-rel)
2. failover 10.3.121.112
3. stop 2 nodes and upgrade them on 2.0.1-112

result:
for some reason the node 10.3.121.113 does not start
panels Active Servers and Pending Rebalance reversed or show nonsense( see screenshots)

I tried to play with failover, add back, rebalance, start manually 10.3.121.113, etc. but it did not help

server's logs, tests logs and some screenshots are attached
