Django 1.8 admin support hacks broke create_choices_on_the_fly example and
probably some other wicked JS things in user projects.
Note that we have also extracted django admin specific hooks from widget.js
into django_admin.js. So if you have custom JS loading in the admin instead
of `{% include 'autocomplete_light/static.html' %}` then you should update
it to include django_admin.js in django admin.
