docker-compose instructions don't work with Docker Compose version v2.0.0-rc.1

[fgregg]

Running docker-compose as directed in the README.md failed:

Error response from daemon: pull access denied for bga-payroll, repository does not exist or may require 'docker login': denied: requested access to the resource is denied

This worked

> docker-compose up app -d --build
...
> docker-compose up -d --build

It's because there building the app is what builds the bga-payroll image, which other parts of the docker-compose depends on.
