Description
If there are several copies of a LOST partition, resetLostPartitions() will leave all of them in the cluster as OWNING.
Scenario:
1) Start 4 nodes, a cache with backups=0 and READ_WRITE_SAFE, fill the cache
2) Stop one node - some partitions are recreated on the remaining nodes as LOST
3) Start one node - the LOST partitions are being rebalanced to the new node from the existing ones
4) Wait for rebalance to complete
5) Call resetLostPartitions()
After that the partitions that were LOST become OWNING on all nodes that had them. Eviction of these partitions doesn't start.
Need to correctly evict additional copies of LOST partitions either after rebalance on step 4 or after resetLostPartitions() call on step 5.
Current resetLostPartitions() implementation does call checkEvictions(), but the ready affinity assignment contains several nodes per partition for some reason.
