Fix: Display proper HVAC operation

[nyirsh]

Description

After updating to the latest version I noticed that my thermostat in KH showed "Cooling off to X" despite being in the HEAT state, confirmed by the Alexa app too.

The code was looking for the first entry in the state that matched the namespace Alexa.ThermostatController.HVAC.Components with name being either primaryHeaterOperation or coolerOperation, without considering its actual status. In the json returned by my Alexa API there were two entries matching those criteria, but the coolerOperation one appeared first and got therefore matched as the current state despite being OFF

...
  {
    "namespace": "Alexa.ThermostatController.HVAC.Components",
    "name": "coolerOperation",
    "value": "OFF"
  },
...
  {
    "namespace": "Alexa.ThermostatController.HVAC.Components",
    "name": "primaryHeaterOperation",
    "value": "STAGE_1"
  },

I changed the code to match any entry that is not set to OFF, built and test locally and the current state is now properly displayed.

I can confirm this is happening to me too. Thank you for this and I hope this can be merged soon!
