This removes all error-catching from the test scripts. If unit tests
fail, the script will exit immediately. The error catching functionality
was not working correctly using the sh shell in Alpine inside the
containers, and so CI was allowed to continue after test failures.
Add a command to the test script to output up-to-date Vue component
templates. Most of the Vue component tests rely on HTML templates built
from Jinja.
The submodule is a leftover from when this project was intended to work
as a series of microservices. It was meant to provide common
functionality to the builds for every microservice. That's no longer the
case, and the submodule is a pain-point both in on-boarding new
developers and running the Docker build.
