Naming a project 'info' introduces invalid redirects from web GUI

Summary

Having a project (repository) named as info introduces invalid redirects when using GitLab web UI to browse commit history. Affects both - GitLab cloud service and an Omnibus installation.

Steps to reproduce

1. Create a project with a project name info under any group using GitLab's web UI (select to Initialize the repository with a README)
2. Go to 'Repository' -> 'Commits' web page
3. Select the 'Initial commit' to open its details
4. Cancel the HTTP basic authentication dialog or enter your user's credentials (doesn't matter)

Example Project

pu13/info@c099c153

What is the current bug behavior?

Upon opening the commit details the user is presented with basic HTTP authentication dialog, which is due to front end scripts firing an HTTP GET to <gitlab_domain>/<group_name>/info/refs which is being redirected to <gitlab_domain>/<group_name>.git/info/refs which in turn presents with basic HTTP authentication dialog which fails if attempted or can be cancelled. The user is then presented with a message Something went wrong while fetching branches

What is the expected correct behavior?

The HTTP GET for <gitlab_domain>/<group_name>/info/refs fired from the commit history details view should not be redirected to <gitlab_domain>/<group_name>.git/info/refs, the HTTP basic auth dialog should not appear and the error message should not appear

Relevant logs and/or screenshots

Output of checks

This bug happens on both - GitLab.com AND Omnibus installation

Possible fixes

Either routing rules are incorrect or the logic in the back end confuses the request with git over HTTPS
