Work Description: adoroszlai commented on pull request #1238: HDDS-1921.
TestOzoneManagerDoubleBufferWithOMResponse is flaky
URL: https://github.com/apache/hadoop/pull/1238
## What changes were proposed in this pull request?
Currently `testDoubleBuffer` waits for a specific transaction count and
checks `lastAppliedIndex`, which is updated last in `flushTransactions` on
another thread. I guess this may be the cause of flakiness. By swapping the
order in the test, we ensure that when the wait is over, all operations
(transaction count increase, etc.) are done.

## How was this patch tested?
Ran `TestOzoneManagerDoubleBufferWithOMResponse` a few times.
