Remove warning deprecated django methods (#220)

* Remove deprecated providing_args argument

RemovedInDjango40Warning: The providing_args argument is deprecated.
As it is purely documentational, it has no replacement. If you rely
on this argument as documentation, you can move the text to a code
comment or docstring.

* Remove deprecated url in favor of re_path

RemovedInDjango40Warning: django.conf.urls.url() is deprecated in favor
of django.urls.re_path()
