Description
It seems commit 0dd737a719cfbd3bc11ff6f2b90161883fcebea0 introduced a regression in the following case:
- the application has migrations
- the application has initial_data
With this configuration Django will crash before any test is run.
This is caused by the initial_data being loaded at the end of the flush while the migrations did not create the associated tables yet:

I saw that but the documentation mentions it is deprecated, not unsupported.
I intended to set the bug as a documentation one but that would break the deprecation policy.

Yes, it a backwards incompatible change if an application uses migrations. It's also mentioned in the 1.7 release notes.

Thinking a bit more about this, I should probably close this bug and open a new one stating that flush command should not install initial_data for application that have migrations.
I created a dummy project (one app with a model and initial data) and here's what flush gives:
(django17_test) air-de-xavier:demo xordoquy$ python manage.py flush You have requested a flush of the database. This will IRREVERSIBLY DESTROY all data currently in the '/Users/xordoquy/django17_test/demo/db.sqlite3' database, and return each table to an empty state. Are you sure you want to do this? Type 'yes' to continue, or 'no' to cancel: yes Installed 1 object(s) from 1 fixture(s)
If Django doesn't install initial_data for apps with migrations then we have a bug in the flush command - which is called by the tests.

Note that initial data isn't supported if an application has migrations. It may be worth throwing a more informative error message though.
