get_url returns url for wrong language

[Toasterson]

Bug Report

Environment

Zola version: 0.17.2

Expected Behavior

When using

<a href="{{ get_url(path=current_path, lang="de") }}">Deutsch</a>

The German Language link always points to the correct german link.

Current Behavior

In my current setup at https://gitlab.com/Toasterson/atelierwegi I have set the default Language = "de" and I am trying to get the Url of the current path for a simple language switcher. When I am in the default language every link is as expected. Once I Switch to english however the german language link is also a link to the english language. So when lang="en" in the template the language does not get correctly changed in get_url.

Step to reproduce

See https://gitlab.com/Toasterson/atelierwegi but basically.

1. Set default_language="de"
2. Be on a English page
3. Use <a href="{{ get_url(path=current_path, lang="de") }}">Deutsch</a> to create a language link to the German version of the page.
4. The link to the German version also now links to the english version

See https://atelierwegi-toasterson-620f5f93159cd6c95174bf09bc660c027f857d5e.gitlab.io/en/ Where the Link "Deutsch" in the upper left hand corner should be pointing to "/" but is pointing to "/en"

The path arg in get_url refers to the markdown file, not the URL path. I'm not sure why it doesn't error but to get it to work like you need you can do:
