Delete old MQTT brokers

Well I finally got the MQTT binding to work in my openhab 2 instance.
But since i have messed around with a lot of different solutions, and had some troubles regarding old owner privileges, I installed and removed the MQTT binding a lot of times.

Now it’s working just fine, but in the logs I can see that all of the old different mqtt clients I tried using is still in there trying to connect to my mqtt broker.

I’ve tried restarting openhab, deleting the mqtt.cfg and restarting openhab again, nothing seems to work. I also tried upgrading from 2.1.0 to 2.2.0.

Any thoughts about how to reset something to get rid of the old connections??

This is output from my log

I see that this topic: Mqtt: get rid of old config actually has the same problem as me. Anyway to get in somewhere and delete that old config files ?
