Refactor (Object) Framework unit tests
Currently most of the Object Framework's tests are rather functional tests than unit tests. Even worse, most of them depend on a real package, the "TestPackage".The tests should be refactored so they
- are true unit tests
- don't depend on another package but come with their own fixtures
Additionally get rid of using the object manager and/or factory of the "outer" FLOW3, making it possible to run the tests completely without needing a FLOW3 instance.
