Template - failed service call does not mark unavailable

The problem

In this triggered template with a service call, if the service call fails some errors are logged and the template value is not updated and retains it's prior state.

I would expect the service call failure to cause the template to go unavailable.

In this specific case, the template is calling to get hourly weather data and the internet was disconnected. So the service call failed but the template state did not update; rather it retained it's old value.
