send these messages out when busy, and preferably not when trying to
print formatted output.

Addressing #2879. The M115 report should display `MACHINE_UUID` but it
always displays `UUID`.

Addressing #3085. If the target_temperature is set directly it never invokes or disables the timer set in `start_watching_heater`, so after _stopping a print_ or turning off _all heaters_ you could get a “Heating failed” error.
