Update django-q to fix migration error

[lydiascarf]

Overview

We have not been able to run migrations in newly built VMs without getting an error. The error gives you a fix, but updating django-q to a recent version stops the error from occurring in the first place.

Testing Instructions

• Follow the README steps
• You should see no error when running migrations

Checklist

• [x] Add entry to CHANGELOG.md

Resolves #808
