After docker restart nginx start before mobydock

[jeckep]

to reproduce:
sudo systemctl restart docker

Because nginx starts first it cannot get access to mobydock volume and therefore cannot server static content. Looks like something wrong in systemd units files. But if we stop mobydock nginx restarted too and after mobydock as expected.
