Confusing error in startmigration --initial if the directory already exists

[jacob@…]

If you issue startmigration --initial on an app that already has a migrations directory but doesn't have an __init__.py, you get a confusing error:

(endorsements)jacob@dorkbook:~/Projects/endorsements$ ./bin/django startmigration endorsements --initial
Traceback (most recent call last):

[In this case I already had a "migrations" directory from a previous migration tool; it contains a bunch of SQL files, but no __init__.py.]

South should detect this situation and either create the needed empty __init__.py or give a more clear error.

Fixed in [95], by creating the init.py.

I meant __init__.py, of course. Formatting fail.
