test with SQ 7.6

[guwirth]

fix directories metric

• https://community.sonarsource.com/t/pre-sq7-6-different-directories-metric-value/6190
• In SQ 7.6 the old “Maven/Java like” filesystem layout has been replaced by a more modern hierarchy, without modules, but with a hierarchy of folders (instead of having flat package-like folders).
• This new approach will change the value of the metric “directories” because this metric count the number of directory “nodes” in the SonarQube component tree. This is misleading since I guess most people expect the value to be the number of physical sub-directories. In my example above, pre-7.6 value would be 3, and post 7.6 value will be 5 (another pitfall of this metric is that folders containing test files are not counted).
