syncdb does not import 'management' module from external apps

[jaap@…]

What steps will reproduce the problem?:

1. Add defaultsite (​http://pypi.python.org/pypi/django-defaultsite/1.1) to INSTALLED_APPS
2. Run syncdb
3. Check the created site object

What is the expected output? What do you see instead?:
I expected a site object based on my settings for defaultsite. Instead I see the standard example.com site.

What may cause this:
South overwrites Django's built in syncdb command. Even though in the background the old command still gets called, the following does not always work:

​http://code.djangoproject.com/wiki/Signals#Howsignalswork

whenever manage.py syncdb is run, it loops through every application in the
INSTALLED_APPS setting, and looks to see if any apps contain a module called
management; if they do, manage.py imports them before installing any models,
which means that any dispatcher connections listed in an app's management module
will be set up before model installation happens.

I suspect the reason for this is that South builds its own list of apps to sync (apps_needing_sync) based on django.db.models.get_apps().

In my case defaultsite, doesn't provide any models by itself. Therefore it doesn't get included in the lists of apps sent to the 'real' syncdb command.
