#24588: Improve handling apps without migrations while running migrate command.
-----------------------------+----------------------

-----------------------------+----------------------
Consider situation - https://pypi.python.org/pypi/django-contrib-
comments/1.5 does not have a migration inside.
It depends on Content-Type model.
So we get something like:
{{{
claudep: the traceback shows that the exception happens when syncing apps
without migrations
[4:23pm] knbk: that "worked" with a big disclaimer on 1.7 but was
unsupported, but somehow breaks on 1.8
[4:23pm] claudep: so the issue is "a unmigrated app depends on an app with
migrations"
}}}
The error is `django.db.utils.ProgrammingError: relation
"django_content_type" does not exist`.
Steps to reproduce - simply add `django_comments` to clean project and run
`python manage.py migrate`. (But, I can reproduce with on postgres, but
not on sqlite for example).
We need to improve handling apps, that does not have a migration, and show
more user-friendly error rather than throwing exception, which user must
investigate.
