Fix loss of response type information in Fetch API

<!-- Please describe your changes on the following line: -->
Avoids mapping response types that are distinct according to [the spec](https://fetch.spec.whatwg.org/#concept-response-type) to fewer response types. Also updates test expectations to match that we now pass tests that check the response type.
