Commands from the README don't work, quiver integration broke the master probably

* Python version: Python 2.7.12
* Operating System: Ubuntu 16.04

### Description
I ran the commands from the README. The migrate failed, look at the backlog below. When I revert commit 5d92929640c6280ffd8f4f56f6f2361b4246939b it works. Quiver integration broke the master probably.

### What I Did
```
user@server$ ./manage.py migrate
