in replica=1 number of replica items not equal to active items after stopping the rebalance

test case:
rebalancetests.StopRebalanceTests.stop_rebalance_1_replica

cluster 6 nodes.
add 200k items
remove one node and hit rebalance - stop rebalance when its making progress

after waiting few minutes # of active items should be equal to # of replica items
