FK id is not used in update_or_create when id is not used directly

Description (last modified by Mariusz Felisiak)

Let's say you have a table

class Foo(models.Model):
    obj = models.ForeignKey('Bar', on_delete=models.CASCADE)
    x = model.IntegerField()
    y = model.CharField(length=10)
    class Meta:
        unique_together = ('obj', 'x')

When you use Foo.objects.update_or_create(obj=instance, x=1, defaults={'y': 'test'}), the SQL generated will omit the obj_id from WHERE clause. On the other hand, when obj_id=10 is used, it is used in WHERE clause.
