add PUT Location header test

A PUT which creates a resource is required to have the server return HTTP status 201 Created, and the new test verifies this.

Is the server also required to provide Location in the response headers? This new test issues a warning if Location is not provided. If the resource is located at the same URI to which the PUT was sent, is Location required?

RFC9110

15.3.2. 201 Created

The 201 (Created) status code indicates that the request has been fulfilled and has resulted in one or more new resources being created. The primary resource created by the request is identified by either a Location header field in the response or, if no Location header field is received, by the target URI.

I do not think Location is required for PUT when 201 Created is returned and the target URI for the resource is the same URI as was sent in the PUT.

Should I submit a PR to remove the warning if Location is not included in response to the new put_location test?

Oh good catch, thanks for reviewing @gstrauss (I messed up the commit message for that commit too... annoying)

Yes please a PR to remove the warning would be great!
