Issue 282: Duplicate/missing Aggregates
Project Member Reported by jmil...@cristoreyny.org, Feb 13, 2012
Aggregates were somehow duplicated for TC's World Literature course.

unique_together would catch the duplicates getting created, but it'd cripple future use of Aggregates.

Replacing get() with filter() and logging an error if multiple returned is okayish.

Removing customary blanket try/except from appy generator would also catch this stuff before humans do.

Sometimes Aggregates aren't created during import: e.g. TC's Algebra 1, Session 1.

Dev sever doesn't interrupt import if user closes page. Maybe wsgi sees the socket close and kills the thread? Bad if so.
