  Bug#22728 Handler_rollback value is growing
   - The handler_rollback value is not growing, but the testcase
  does not work as handler_rollback is not cleared by "flush status"
  Thus we need to record before and after value and do a compare

    FLUSH STATUS does not clear all status variables(at least not Handler_rollback)
    Change the test case to records the value before and after and do a compare to check that 
    handler_rollback has not changed
