    Update MetadataTableUtil.java
    
    Outputting every "loaded" entry in the table is excessive, especially for tables with
multiple simultaneous bulk imports and multiple references to the same file.  This has been
seen to cause performance problems.  Even when the log level was reduced, there was blocking
within log4j.  By doing that check once outside the loop and only logging at trace level,
we have seen bulk import performance improvements.
