List project group titles instead of URLs

Previously, for non-admin users, project group URLs were displayed
instead of titles in the 'Project Group' field, and those URLs
would display instead of titles when clicked. This meant that
project groups would have different titles for admin and non-admin
users. This patch displays the titles for everyone.
