Replaced unique_together with UniqueConstraint in models that covered nullable fields as in unique_together database indexes don't work where subgroup=None. So added conditional unique index handling invalid duplicate Count data. Added 0015_clear_duplicate_counts migration to handle existing data that violates the constraints. Also corrected a test case in test_counts.py which didn't clear its state properly and thus was accidentally taking advantage of this database schema bug.
