We had someone in IRC trying to use a custom AppConfig with an application
that was installed to a subdirectory called "apps". The AppConfig wasn't
being picked up, and the import_module machinery was throwing errors. I've
replicated this locally too.
Application at: project/top/drill/
{{{
INSTALLED_APPS = [
'top.drill', # with default_app_config
'top.drill.apps.DrillConfig', # without default_app_config
]
$ ./manage.py shell
Traceback (most recent call last):
File "./manage.py", line 9, in <module>

packages/django/core/management/__init__.py", line 427, in

packages/django/apps/registry.py", line 85, in populate
app_config = AppConfig.create(entry)

}}}
Problem happens using default_app_config or by referencing the AppConfig
from INSTALLED_APPS. I suspect there's a problem related to importing
modules when the application isn't in the project root directory.
I think that https://code.djangoproject.com/ticket/23470 was the same
problem, but it was never fully investigated.
