Motivation:

When a pull request is created, the ci github action
always failed. This defeat the whole point of a ci.

Modification:

- add a github action that will be trigger only on a
    push to the master branch
- add a test for a build that will generate files that
    will later be used for creating an artifact
- move the sonarqube scanner from post test command to
    `test:sonarqube`

Result:

- no more build fail cause by sonarqube when a pull
    request created
- test for build is added and run
- test for sonarqube is run only when on a push
    request
