mqtt: not receiving any payloads

[lynxis]

v4runa didn't received any mqtt payloads. So the doorkicker didn't worked anymore.
The mqtt connection seemed healthy, at least ping/pong messages came through.

There were still a lot of log messages. Maybe from a leaked mqtt connection?

The problem lies in amqtt. It doesn't properly handles reconnects or not even disconnects.
See Yakifo/amqtt#153 which fixes at least the disconnects and we can do the reconnect on our own.
