If 'restrictedmodulesfor' is set to 'All courses', 'restrictbydefault' is set and 'defaultallowedmodules' are selected, courses created by a user with 'course creator' role don't contain any modules.

Reproduce:
1. visit 'Security' 'Modules security' in the 'Site Administration' menu
2. set 'restrictmodulesfor'
3. set 'restrictbydefault'
4. select some 'defaultallowedmodules'
5. save changes
6. change to a user with a 'course creator' role
7. create a new course

Result:
If you want to edit the course afterwards you don't have any ressources/activities available.

Expected:
I would expect the course to have at least the defaultallowedmodules in it.
