Fix jenkins auth

WebHooks currently support basic auth in the webhook URL - `http://user:pass@example.com`. With the Jenkins CI service the webhook is fired correctly when the project URL is in this format. However, the build status was unable to poll because auth was not used correctly.

This merge requests implements the basic auth strategy much the same as the web hook does. See https://gitlab.com/subscribers/gitlab-ee/blob/master/app/models/web_hook.rb#L34 for reference.
