#2415: AutomaticManipulator with foreign keys and unique_together fails

------------------------------+---------------------------------------------
When attempting to use model.AddManipulator() on a model with both
unique_together and a foreign key reference, the AddManipulator fails with
the following traceback.
Removing either the foreign key, or the unique_together, and
.AddManipulator() proceeds without issue.
{{{

The model in question is :

note, as a description.
