Rework CI pipeline

- coverage is now performed as 1 step (getting rid of cache/artifacts mess at
  the moment)
- unit tests run now ensures that build-dir exists (again to avoid
  cache/artifacts troubleshooting)

Cache/artifacts may be useful when dealing with integration tests but it should
be better to keep things simple by now
