------------------------------------------------+------------------------
When you misspell the name of the AppConfig subclass in `INSTALLED_APPS`,
it currently retriggers the exception for importing the class as a
module[1]. This disregards that the mod_path (all but the last part of the
import string) is importable and defines an AppConfig subclass.
In my case, I had a config at `courses.apps.CoursesConfig`, and included
`'courses.apps.CourseConfig'` (no 's' in Courses) in `INSTALLED_APPS`.
I think we can provide a better error message when the mod_path
(`courses.apps`) is importable and has `AppConfig` subclasses, something
like "'courses.apps' does not have a class 'CourseConfig', did you mean
'CoursesConfig'?".
