    LUCENE-10574: Fix test failure.
    
    If a LogByteSizeMergePolicy is used, then it might decide to not merge the two
    one-document segments if their on-disk sizes are too different. Using a
    LogDocMergePolicy addresses the issue as both segments are always considered
    the same size.
