gopher test updates do not match spec updates

[domenic]

#453 and web-platform-tests/wpt#19770 do not match.

First, the tests expect gopher to also be removed from the list of origins which get serialized nicely: https://url.spec.whatwg.org/#concept-url-origin

even after that, the following tests fail:

 Web platform tests › setters › protocol › <gopher://example.net:1234>.protocol = "file" 

    Expected value to be equal to:
      "gopher://example.net:1234/"
    Received:
      "gopher://example.net:1234"

Web platform tests › setters › protocol › <ssh://me@example.net>.protocol = "gopher" 

    Expected value to be equal to:
      "ssh://me@example.net"
    Received:
      "gopher://me@example.net"

I think these latter two are test issues. The former could either be a test or spec issue, depending on whether people think #454 is correct.
