Queries fails with error {"error":"error","reason":"inconsistent_state"}

can be reproduced by test:
./testrunner -i resources/jenkins/centos-64-7node-viewquery.ini get-logs=True -t viewquerytests.ViewQueryTests.test_employee_dataset_startkey_endkey_queries_rebalance_incrementaly,skip_rebalance=true

Steps to reproduce:
1. Load data and query simultaneously, data is loaded
2. Start rebalance in 1->2 nodes and run query, wait for rebalance
3. Start rebalance in 2->3 nodes and run query, wait for rebalance

{"error":"error","reason":"inconsistent_state"}

error appears
