Fix locals comment in answers/_new_edit partial

- This change updates/corrects the commented locals in `app/views/answers/_new_edit.html.erb`.
- Prior to this change, there were conflicting comments listing the available locals. `plan` does not appear to be one of them. Also, `app/controllers/answers_controller.rb` reveals that `base_template_org` is one of them.
