Unit does not power off with MQTT JSON Command

[alexschwantes]

Even if the unit is off, and you send the {"state":"OFF"} message to RGB/XXXXXXXX/json/set, it results in turning the unit on. Unit can be turned off with IR though. The problem lies in the callback method which always sets the startFade=true.

I have a fix I will create a pull request for. I just did the minimum to fix this, although there are a few too many nested if statements in that method, might be cleaner to rework it a bit.
