Cody Cutrer 959154fef8 optimize Account#associated_courses 
query profiling indicates a subquery is actually 2x as fast as a join,
as it does the uniq-ing prior to loading the actual course rows.
it also makes dealing with this association easier, cause it's no longer
a DISTINCT

test plan:
 * viewing the list of courses for an account should still work
