Hello. When a server issues a 303 See Other, the request should be repeated, 
but the method should switch to GET. This shows up correctly in the logs:


* We are completely uploaded and fine
* Mark bundle as not supporting multiuse

< HTTP/1.1 303 See Other
[...]

* Ignoring the response-body
* Received 147 B chunk
* Connection #0 to host localhost left intact
* Issue another request to this URL: 'http://localhost:3000/...'
* Switch to GET
* Found bundle for host localhost: 0x1f79944cb60 [serially]
* Can not multiplex, even if we wanted to!
* Re-using existing connection! (#0) with host localhost
* Connected to localhost (127.0.0.1) port 3000 (#0)

However, unfortunately, Insomnia then continues with the same method, which
would be correct for a 307, but not 303.

> POST ... HTTP/1.1
> Host: localhost:3000

> PATCH /api/profile/v1 HTTP/1.1
> Host: localhost:59223

* upload completely sent off: 21 out of 21 bytes
* Mark bundle as not supporting multiuse
