    fix some stats monitor metrics
    
    Descriptions of the changes in this PR:
    
    The journalStats.getJournalQueueSize increase once and decrease twice, so 
this stat metric will be negative.
    
    It increases in `logAddEntry` function and decrease in `QueueEntry recall` 
methord and Journal main thread run methord.
    
    so we should delete the decrease in journal main thread run methord.
    
    ```
    queue.put(QueueEntry.create(
                    entry, ackBeforeSync,  ledgerId, entryId, cb, ctx, 
MathUtils.nowInNano(),
                    journalStats.getJournalAddEntryStats(),
                    journalStats.getJournalQueueSize()))
    ```
