add_column fails for unique ForeignKey or OneToOneField

[john.firebaugh@…]

    def test_add_unique_fk(self):
        """
        Test adding a ForeignKey with unique=True or a OneToOneField
        """
        db.create_table("test_add_unique_fk", [
            ('spam', models.BooleanField(default=False))
        ])
        db.start_transaction()
        
        db.add_column("test_add_unique_fk", "mock1", models.ForeignKey(db.mock_model('Mock', 'mock'), null=True, unique=True))
        db.add_column("test_add_unique_fk", "mock2", models.OneToOneField(db.mock_model('Mock', 'mock'), null=True))
        
        db.rollback_transaction()
        db.delete_table("test_add_unique_fk")

With a sqlite database, this produces:

OperationalError: table test_add_unique_fk has no column named mock1

when trying to create a unique index on column 'mock1'. It should instead be creating the unique index on column 'mock1_id'.
