21833	Use of new Settings.is_overridden() method breaks if settings.configure() is used	Carl Meyer	nobody	"There are two ways to set up Django's settings; one is by passing a settings module to the `Settings` class, and the other is to call `django.conf.settings.configure()` with keyword arguments.

In d818e0c9b2b88276cc499974f9eee893170bf0a8 (the new checks framework) a new `is_overridden` method was added to `Settings`, and in the ""check_1_6_compatibility"" check, it is called on `django.conf.settings`. But if `settings.configure()` was used, `django.conf.settings` is not wrapping a `Settings` instance, it is wrapping a `UserSettingsHolder` instance. And thus the ""check_1_6_compatibility"" check dies with ""AttributeError: 'module' object has no attribute 'is_overridden'""."	Bug	closed	Core (Other)	dev	Release blocker	fixed			Accepted	0	0	0	0	0	0
