'reporters' unable to clone over http

Created by: munkyboy

Steps to reproduce:

• using gitlab 3.1.0
• create a user and give them 'reporter' access to a repo
• as that user, try to clone the repo over http

Expected results: The repo should clone over http.

Actual results: The repo does not clone.

Notes: When promoted to 'developer', cloning over http works fine. Reporters are able to clone over ssh.
