Hi, [~sergey-chugunov] Please take a look.
This test falls for two reasons:
1) If node fail event occurs before local join, *DiscoveryWorker* hangs.
2) If all servers left cluster oldest client notifies all clients. Oldest
client receives events data and adds *ZkNoServersMessage*. If new events are
added at this time, the events data version will change and cause
*BadVersionException*.
