Translated displays don't work with OrderedDict dict_class

[spapanik]

Steps to reproduce:

>>> from collections import OrderedDict
>>> from django.utils import translation
>>> from django.utils.translation import gettext_lazy as _
>>> from extended_choices import Choices
>>> STATES = Choices(
...     ('ONLINE',  1, _('Online')),
...     ('OFFLINE', 2, _('Offline')),
...     dict_class=OrderedDict,
... )
>>> translation.activate('fr')
>>> STATES.displays
Traceback (most recent call last):
  File "/usr/local/lib/python3.6/code.py", line 91, in runcode
    exec(code, self.locals)
  File "<console>", line 1, in <module>
KeyError: 'En ligne'

Thanks for your report. I guess this one won't be easy.

I don't have time right now, but won't forget to look at this as soon as I can.
