Missing Trailing slash in HomePage link when lang != default

[itzwam]

Describe the problem:

Main page links to a relative path without the trailing Slash, cuz it's based on baseURL instead of site.Home

Steps to reproduce:

1. Add 2 langs
2. Serve built pages using a strict webserver
3. Switch to another lang
4. HomePage link in header is missing trailing slash -> 404

Observed Results:

• Link to inexistant page

Expected :

• Link to existant page
