10290 FIX Temperature check: fix rendering crash and reporting mismatch

When a check sends a device-specific levels in a specific format the temperature rendering function of the service display could crash due to a type mismatch. This werk fixes this crash.

Upon fixing this crash another bug was discovered and fixed. In the case of user specified levels being set and the service being in mode "Use your own levels if present, otherwise the device's", the device levels were not ignored and thus the wrong levels were checked. This is now fixed as well.

No additional action is needed.
