Removing a OneToOneField Tries to add ID before before removing old PK

[ed@…]

If you remove a OneToOneField? from a model, postgres produces the following error:

File "c:\projects\wpf\eggs\django-1.0.2_final-py2.6.egg\django\db\backends\util.py", line 19, in execute
    return self.cursor.execute(sql, params)
psycopg2.ProgrammingError: multiple primary keys for table "edu_core_address" are not allowed

Workaround is to change the order in the migration and move the drop of the old PK before the add of the new PK (id).

Yes, this is one of the general issues with the ordering of stuff in startmigration. We're reworking it in 0.7, so assigning it there.

South 0.7 now always puts field deletions first, so this bug is solved.
