Catch the TypeError in sensors page

On the sensors page, there is the below error and some sensors are missing:
Uncaught (in promise) TypeError:
Cannot read property 'LowerCaution' of undefined

The root cause is that some sensors do not support all these
Thresholds properties, add the checking to catch such errors.

Tested:
These sensors in redfish/v1/Chassis/$id/Sensors/
can be displayed in sensors web page
