MQTT heartbeat not updated.

[rkuijer]

Bug description
Currently using version 2.2.1b3 to verify the solution of issue #369, which is OK. Thanks for that!
During the first tests, I saw that the heartbeat info to MQTT isn't updated. The first indication was that there was a mismatch between the amount of MQTT publish fails, 2 on the AMS-ESP and 1 on the MQTT broker. When I looked at the time stamp came to the conclusion that it's only updated during bootup.

Steps to reproduce
No special steps are needed just boot the EMS-ESP and connect to an MQTT broker with Home Assistant Format.
Clean session and retrain flag are checked.
When you watch the MQTT broker you will see that the heartbeat info won't be updated.

Expected behavior
Interval update of the heartbeat information.
