nixos/paperless-ngx: fix startup order

Browse Source 
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"
