When an admin is viewing someone else's review request, they now have a

choice between viewing it as if they were a regular user, and seeing

unpublished draft data.
This change makes it so when a new draft is created by the admin, we

switch to the view-draft mode.

Made changes to a review request (setting draft fields, creating

attachments) and saw that the draft banner appeared, the notice about

viewing an unpublished draft appeared, and that the URL in the browser

changed to include the ?view-draft=1 query parameter.
