[bug] propertyKeyName should be used instead of propertyKey if it exists

[AlCalzone]

Found several locations where propertyName is used in place of property, but the same does not happen for propertyKeyName.

Also, this is completely wrong I think (propertyName instead of propertyKeyName):

propertyKeyName is missing completely here:
https://github.com/zwave-js/zwavejs2mqtt/blob/master/lib/ZwaveClient.js#L814

This should also append the propertyKey(Name) to uniquely identify the value:
https://github.com/zwave-js/zwavejs2mqtt/blob/master/lib/ZwaveClient.js#L819

This confuses propertyKey with property (should be the other way round):
https://github.com/zwave-js/zwavejs2mqtt/blob/master/lib/Gateway.js#L1534
and
https://github.com/zwave-js/zwavejs2mqtt/blob/6e2a0f726aa8f14bc06258860c002e6373697f05/lib/Gateway.js#L1697-L1701

This looks up the sensor type manually:
https://github.com/zwave-js/zwavejs2mqtt/blob/6e2a0f726aa8f14bc06258860c002e6373697f05/lib/Gateway.js#L1569-L1571
(I thought we added the ccSpecific stuff for this?)

This should probably use property instead of propertyName:
