[apollo-datasource-rest] Http cache semantics not honored as expected

[Jolville]

Package version
"apollo-datasource-rest": "^0.6.11"

Expected behavior
When a GET request is made using RESTDataSource and a ttl value is provided, the response is cached for the given time.

const response = await this.get('some-path', {}, { cacheOptions: { ttl: 600 } });

Then a second request is made while the request is still cached, but the reload option is given:

const response = await this.get('some-path', {}, { cache: 'reload', cacheOptions: { ttl: 600 } });

I am expecting this will fetch the response from the datasource and then save the response to the cache with a ttl of 600.

Actual behaviour
The response from the second request is returned from the cache (and the cache isn't updated). I believe that this if statement here should check whether the request needs to be remade regardless of the ttlOverride from the first cached request.

Please let me know if this behavior is deliberate.

Thanks!
