Remove all module-info.java in all unit tests sets (Services)

As defined in https://github.com/hashgraph/hedera-services/issues/6611 all unit tests should be executed on the class path. To do so we should remove all module-info.java from src/test/java.

Read issue 6611 for the requirement that unit tests run on the class path. Search the repository for module-info.java files under src/test/java, remove the test-set descriptors, and verify that the unit-test suites still execute successfully on the class path.
