Redirect loop after testing service settings
Created by: heikobornholdt
When I open the edit page for GitLab CI-Service of a GitLab Project (http://example.com/foo/bar/services/gitlab_ci/edit), click to "Test settings", wait for page to refresh and click "Test settings" again, it will result in a "redirect loop".
I believe, the redirect_to :back instruction (https://github.com/gitlabhq/gitlabhq/blob/2ed7cbfba4ff3c6a4cf3e72515a0375544998de0/app/controllers/projects/services_controller.rb#L31) causes this problem.
Now I have dozens of pending builds on my GitLab CI
