Hide repo plan row for custom SCM services
Hide repo plan row for custom SCM services

The add repository JS refactor change accidentally made the "Repository
row" show for custom (i.e., non-hosting services) repositories. This
patch reverts that change. This is a trivial fix.

Testing Done:
- Viewed the add repository page for a custom repository; the repository
  plan row was not visible.
- Viewed the add repository page for a repository that supported hosting
  plans; the plan row was visible.
