Fix range responses (#198)

Fix range responses

### Motivation

Fixes #197, broken range responses, such as `4xx`.

### Modifications

Fix the bug, seems to have been some old copy paste gone wrong, and we didn't have a test for it.

### Result

Now range responses work again.

### Test Plan

Changed one of the status code responses to be a range response, updated fixtures.
