Running eg `./manage.py dumpdata django.contrib.auth` fails with
`CommandError: Unknown application: django.contrib.auth`. Instead, you
need to call the command with just `auth`.
This is because it calls through to `apps.get_app_config` which does not
expect a fully-qualified package name.
There is a similar problem with other management commands that take an
app's name.
There are a handful of approaches to fixing this:
1. `apps.get_app_config` should split a package name on dots, throw away
all but the last token, and use this for looking up the app. I've not
thought through all the consequences of this -- could an app name
legitimately contain dots?
2. As for 1, but only if the package name begins `django.contrib`.
3. When `apps.get_app_config` raises a `LookupError`, it could check to
see whether its argument contains dots, and its message could be something
like `No installed app with label 'x.y.z'. Did you mean 'z'?`.
4. Whenever a management command calls `apps.get_app_config`, it could
strip off `django.contrib.` if present.
I'm happy to code up a fix if/when the right approach is settle on.
