Fix instance level project templates QA spec

Improve performance of login test and remove comments

See merge request gitlab-org/gitlab-ce!27515

The comments were TODOs but there were no explanation of what

that the user is logged in.

Finally, as Robert C. Martin said once:
"After you check in a TODO comment it turns into a DON'T DO"
