Fix RemovedInDjango110Warning

[IllyaMoskvin]

Low priority, but we are getting a lot of notices about deprecated function calls, mostly in various urls.py files. I might be able to address this as part of #283, but I'm posting it here in case I don't get to it for that PR.

@jslootbeek I think you already took care of this with PR #302, but let me know.

Many of these have been fixed, in particular the urls.py issues, by #302, but at least this one still exists:
