Python3 AttributeError with redirect_to_login and lazy LOGIN_URL

[Peter Schmidt]

See discussion on #18776 to decide whether to keep patching symptoms or fix the root cause.

Ran into the same AttributeError: '__proxy__' object has no attribute 'decode'.

Please see attached test_redirect_to_login.diff or ​https://github.com/mathspace/django/compare/error-lazylogin-master which passes under Python 2.7 but throws the AttributeError under Python 3.4

One workaround is to explicitly pass the string form of the variable, i.e.

redirect_to_login(next=..., login_url=str(settings.LOGIN_URL))
