HTTP Status 303 See Other redirects do not use GET

**Describe the bug**
When an API returns a 303 See Other status code, Insomnia will follow the redirect with whatever HTTP Method was used for the original request instead of using the GET method as is standard.

**To Reproduce**
Steps to reproduce the behavior:
1. Make a PATCH request to an endpoint that returns a 303 See Other status.
2. See that the request calls the redirect URL with the PATCH method instead of GET.

**Expected behavior**
The expected behavior is for the URL in the Location header to be called using the GET method.

No source file or test is named in the issue. Reproduce a PATCH request receiving a 303 response, then trace Insomnia's redirect handling to the method used for the Location URL; done means the redirected request uses GET and the behavior is covered by a regression test.
