Broken on django-storages >= 1.14.4

[petrklus]

Due to the change with how .exists() works when used with certain backends, Django-filer is now broken as it relies on .exists to return actual file existence (and not False). This happens for me on S3 backed storage (not locally).

@petrklus Thanks so much for bringing this to attention! For now, django-filer needs to work with django-storages>=1.14.3.

Django has clarified the ways .exists() works in their development branch (https://docs.djangoproject.com/en/dev/ref/files/storage/#django.core.files.storage.Storage.exists) and my understanding is that django-storages will revert to this updated definition in its next minor release.

I suggest to wait for the changes in the next django-storages release and see from there, if filer needs an update.
