Description of problem

After the host reboots, the apps are wrongly deployed.

I have 2 apps currently on the site:
The first a Rails+Postgres app dashboard, with the main domain added to it. (e.g. example.com)
The second a static site mqtt-web, with a subdomain added to it. (e.g. mqtt.example.com)

After rebooting, it appears that the subdomain now points the first app, thus generating a Rails "We're sorry, but something went wrong." page when visited.
The main domain doesn't work with a Bad Gateway error.

To fix this, I have to do a dokku ps:restartall.

This is reproducible every time I restart the server, and will require me to do the above fix before the apps are properly deployed to the respective domains.

Output of dokku report and docker ps -a before/after the dokku ps:restartall

Environment details (AWS, VirtualBox, physical, etc.): AWS EC2 t2.micro, Ubuntu 16.04

How was Dokku installed?: As per README.md

wget https://raw.githubusercontent.com/dokku/dokku/v0.10.5/bootstrap.sh
sudo DOKKU_TAG=v0.10.5 bash bootstrap.sh

How reproducible: Always. Happens every sudo reboot now.

Steps to Reproduce:

1. sudo reboot now
2. Visit domain & subdomain
