Transparent default value for MqttFingerprint2 

I was unable to find any information on where the existing default
MqttFingerprint2 value came from, and can't be sure that someone
doesn't have a key matching it.

For transparency, this patch replaces the default MqttFingerprint2 value
with the result of SHA1("Tasmota") as a "nothing-up-my-sleeve number".
