Fix webhook source identification

GitHub and GitLab both send `$payload['repository']['url']`, but only
GitLab's payload contains `$payload['project']`.

This ensures that the proper URLs are used from webhook payloads and
fixes testing integrations with nonstandard URLs (for example, when
developing integrations in a local instance of gitlab-development-kit).
