URL of "Check it out" button in "Customize your experience" box broken with relative URL installation.
Summary
"Check it out" button in "Customize your experience" box on "Projects" page url omits the relatie URL of our installation.
I have GitLab running on official Docker image and served under a relative URL like https://my.domain/gitlab. When I enter the Projects page (https://my.domain/gitlab/dashboard/projects) and see a box titled "Customize your experience" the button "Check it out" leads to https://my.domain/profile/preferences instead of https://my.domain/gitlab/profile/preferences.
Steps to reproduce
Run GitLab under relative URL. Open the Projects page.
What is the current bug behavior?
After clicking the button I land on non existing page.
What is the expected correct behavior?
The button should open the https://my.domain/gitlab/profile/preferences page.
