[Hotfix] mongo200 upgrade

Hi, i just finsed the mongodb upgrade from mongodb-2.6.12 to mongodb 4.2.3. right now our mongodb runs inside a docker container and uses the new wiredtiger engine. So far all defrag jobs are disabled because they are not needed anymore. I activated mongo200 for LMX and FER again and i can see requests are incoming and im able to get requests from databse in the xAdmin menu under Buchungen --> Anfrage Logs. BR Denny
