[JUNIT] cleaned up Testsuite layout and removed senseless test classes

Updated all test suites and added them to the AllTestSuite class.

This updating should be done by a script the next time to ensure
that all tests are executed by the developer before the CI will execute
them. (which do not need Testsuites to find test classes).
