contenttypes table not created properly

[sagivmalihi@…]

if i have 2 applications - app1, app2 , both with a sub-module sub:
app1/sub/models.py
app2/sub/models.py

then only models from one of the apps will get a row in the django_contenttypes table.

This is because, when processing app2 - in update_contenttypes (contenttypes/manangement.py) first gets all current contenttypes for app1 (\
because the query ContentType.objects.filter(app_label=app.name.split('.')[-2]) returns all the rows for app1 and app2)
and then after inserting all the objects for app2 (which are not present there) - it deletes all the previous objects inserted for app1 because it thinks they're 'stale' (they weren't part of get_models(app2))
