The nixOS test failed sporadically with a timeout.
This is due to a race condition in the startup of
the scheduler vs the task-queue.
The scheduler runs the migration scripts in "pre-start" and
celery isn't available, yet. The celery worker (paperless-task-queue)
was already started by systemd but was unable to connect
(as the migration scripts from "pre-start" still ran).
This fix adds the necessary "after" condition in the systemd
worker unit and adds a test to "paperless"

Standalone mpv doesn't segfault (when directly playing the underlying
media files). I don't know why.
