Prevent turning on tellduslive lights with 0 brightness (#23135)

Browse Source 
* Prevent turning on tellduslive lights with 0 brightness

It was possible for the light compontent to get in a state where the last_brightness was set to zero, and when turning on (by calling turn_on) it would call the TellStick with 0 dim level, ergo not turning on the light.

With this, it will fall back on a 75% dim level if the level is set to zero.

* Wrap long log line over two lines

And using a more proper way of formatting the message

* Fallback to 100% instead of 75%
