FK from `unmigrated` app model to `migrated` app model is not created

[Sergey Fedoseev]

foo/models.py

from django.db import models

from bar.models import Bar

class Foo(models.Model):

    bar = models.ForeignKey(Bar)

bar/models.py

from django.db import models

class Bar(models.Model):

    baz = models.IntegerField()

do ./manage.py migrate

do psql -c '\d foo_foo' test_django

                        Table "public.foo_foo"
 Column |  Type   |                      Modifiers

 bar_id | integer | not null
Indexes:
    "foo_foo_pkey" PRIMARY KEY, btree (id)
    "foo_foo_bar_id" btree (bar_id)

FK is absent.

On 1.8a1 migrate step throws this error:
