refactor: migrate unit tests (on Java) to JUnit 5

Notes:
- only unit tests already written on Java have been migrated. Tests on Spock will be migrated in #1246
- pmd: JUnit4SuitesShouldUseSuiteAnnotation check has been disabled because it's junit3/4 specific
- pmd: JUnitAssertionsShouldIncludeMessage check has been disabled because we use AssertJ assestions

Changelogs:
- https://junit.org/junit5/docs/5.0.0/user-guide/#release-notes
- https://junit.org/junit5/docs/5.1.0/release-notes/index.html
- https://junit.org/junit5/docs/5.2.0/release-notes/index.html
- https://junit.org/junit5/docs/5.3.2/release-notes/index.html
