_attr_target_temperature_low and _attr_target_temperature_high attributes must be initialized otherwise HA CachedProperties doesn't create a backing prop. If they are not initialized, climate will error during setup because we support TARGET_TEMPERATURE_RANGE and it tries to read them. These attributes are not initialized in ClimateEntity like most others, and in a case where the thermostat is not set to auto, they do not get set in async_update either.
