Old versions in Pipfile causing conflict

[sebastian-correa]

Versions in the Pipfile should be bumped, as the old versions of django in use seem to be incompatible with some of the dependencies marked with *. At least in my case, bumping dependencies solved some weird problems with the API.

Ideally, one would then use pipenv sync instead of pipenv install to deploy the exact locked version, so that these issues don't arise again if in the future some library gets updated.
