Nhat Nguyen e098e837f7 Fix testShouldPeriodicallyFlushAfterMerge (#52243)
MockRandomMergePolicy randomly determines if a segment should use a 
compound format. This can cause a force merge performing two merges: (1)
merging to a single segment, (2) rewriting the new segment using the
compound format. If the second merge completes after we have flushed,
then it can flip the flag shouldPeriodicallyFlushAfterBigMerge to true.

Closes #52205
