Title: Fix STUD-1316

This bug affected unpublishing content (and would trigger an error message in
studio). The fix was to uncouple the rendering of the studio_view of an xblock
with the student_view, so that content that wasn't in draft mode already
wouldn't be modified by early rendering of the studio_view.
