[RSPEED-189] Run unit tests in GitHub actions (#20)

* Fix config and history wrong paths

There were a couple of leftovers when we renamed the project from
shellai to command-line-assistant, and also, we were handling how to
create the folders and files in the wrong way.

* Write basic unit tests to get the suite started

* Add github actions pipeline for running tests
