configuring a relative url breaks links

Summary

relative path config breaks link generation when main page is visited by clicking the GitLab logo

Steps to reproduce

1. configure non-root path (https://docs.gitlab.com/omnibus/settings/configuration.html#configuring-a-relative-url-for-gitlab)
2. login
3. click the top left GitLab logo to open the main page (listing your projects)
4. click any project

What is the current bug behavior?

the link does NOT include the configured path, links to the root path which leads outside GitLab

What is the expected correct behavior?

the link includes the configured relative path

Possible fixes

only visit the project list by clicking "Projects" -> "Your projects"
