I think that this line is broken; 37ff75b#diff-46ecae53ba9f8c81d6e2cd0c74251579R115

In my local env (Python 3.5.2, django-stormpath 1.1.0), the first variable in this list created by key.split(self.DJANGO_PREFIX) is an empty string. Here's a screenshot of a debugger attached, with the line broken to illustrate the problem;

I'm not sure when exactly this cropped up, but here's what that sort of operation looks like in my python interpreter;

$ python
Python 3.5.2 (v3.5.2:4def2a2901a5, Jun 26 2016, 10:47:25)
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> 'string_key'.split('string_')
['', 'key']

I'll be submitting a PR in a just a moment.
