…648)

* Don't just mount `spec` folder, but complete `app` folder for tests

This is to ensure that local changes in the `app` folder are reflected
in the Docker container such that newly written tests can be run through
without having to rebuild the whole Docker image.

* Exclude `public/` folder from mount

Also see: https://stackoverflow.com/a/56361190/

* Copy everything to `usr/src/app` for precompiling to work & fix `public/` folder mount
