Fix docker compose up.

[dbernstein]

Description

This update gets the docker compose up command working again.

Before this change I was seeing the following error:

vlc-1    | virtuallibrarycard.Library.customization: (fields.W342) Setting unique=True on a ForeignKey has the same effect as using a OneToOneField.
vlc-1    | 	HINT: ForeignKey(unique=True) is usually better served by a OneToOneField.
vlc-1    | Superuser created.
vlc-1    | Traceback (most recent call last):
vlc-1    |   File "/usr/local/bin/uwsgi", line 5, in <module>
vlc-1    |     from pyuwsgi import run
vlc-1    | ImportError: libexpat.so.1: cannot open shared object file: No such file or directory
vlc-1 exited with code 1

After we we are able to use docker compose up.
