refs MC-118
test plan:
- use a blueprint course with at least one association
- create a blueprint sync with several changes
- once the sync is complete, use the rails console to grab the
database id of that migration
- use the course id of an associated course and go to the following
URL: `/course/:course_id/#!/blueprint/migrations/:migrationId`
- note that a full screen modal showed up displaying the correct
changes from the last sync
- note that closing the modal changes the URL to `/courses/:course_id`
