html5lib currently issues a DeprecationWarning in python ^3.7. This
warning is fixed here:

https://github.com/html5lib/html5lib-python/commit/4f9235752cea29c5a31721440578b430823a1e69

I have spoken with the maintainers (#whatwg on freenode) and they said
that a new release of html5lib is not scheduled as the package is not
actively maintained, but it sounded like they were aware of the issue
and could release a new version. (I did not press further.)

This is a very minor change with no major intended side effects, other
than that it cleans up output while running tests (and presumably from
any clients using the legacy_repository type).

* Fix authentication failure for some APIs

Fixes an issue which occurs when APIs return authentication information in the URLs embedded in JSON responses.

* Test authentication on same host with duplicated credentials

Add test to ensure that basic authentication credentials in request URLs does not break authentication when they credentials match. This test purposefully does not examine program behavior when URL credentials and session credentials are different.
