Usage help of makemigrations command missing argument for app

[bruno.devpod@…]

The makemigrations command usage help shoud show:

Usage: manage.py makemigrations [options] [app_label]

Instead of:

Usage: manage.py makemigrations [options]

As pointed in documentation:

If your app already has models and database tables, and doesn’t have migrations yet (for example, you created it against a previous Django version), you’ll need to convert it to use migrations; this is a simple process:

$ python manage.py makemigrations your_app_label
