Logo link duplicates when base URL contains path

[Anaminus]

When the base URL of the website is configured with a path, the path portion of the logo's URL will be duplicated.

Reproduction:

1. In config.toml, set the baseURL to "https://example.com/foo/bar".
2. Start hugo serve.
3. Navigate to http://localhost:1313/foo/bar/.
4. Click on the logo.

The result is that the page incorrectly navigates to http://localhost:1313/foo/bar/foo/bar/ instead of http://localhost:1313/foo/bar/.

The problem occurs in layouts/partials/theme/logo.html, and is likely caused by passing the .Site.Home.RelPermalink variable to the relLangURL function. Because relLangURL will already include the root, it would appear to be sufficient to pass an empty string instead. For example:

{{"" | relLangURL}}

Thanks @Anaminus and sorry for the delay,
Indeed, url is correct now. (Problem was also in 404.html).
