Fix database error being written to WARN log when installing a fresh Wildfire. It's in the form:
2006.07.06 22:43:11 Error verifying server version
java.sql.SQLException: Table not found in statement [SELECT minorVersion FROM jiveVersion]
This is caused by the fact that Wildfire will try the old version check if other version checks failed first. Instead of logging the error to the warn log, send it to debug.
