Fix SonarQube warnings

targetted:
- Introduced CmResourceAddress (name agreed with Daniel and Priyank)
- Extracted out private method in AltenateIdChecker to reduce complexity
side effects:
- use 'record' java feature as suggested by ItelliJ
- had to uprade spotbugs version to avoid incorrect warning on 'record' equeals method
- convention: added missing 'asserts' in affected testware
- my preference: removed a lot of unnecessary linebreaks in affected testware
- removed redunfant (variation) of a 'delegation' test
