Fix autotune Thermal Protection

Browse Source 
When `THERMAL_PROTECTION_BED` is off but `THERMAL_PROTECTION_HOTENDS` is on, `watch_temp_period` and `watch_temp_increase` are initialized with the values for `THERMAL_PROTECTION_HOTENDS`. Later it is not tested if these values are for the bed or the nozzles.

- Add test.
- Name a constant.

Fix for #10150
