Remove unused method and streamline tests in ScaleReverseTest

Removed the custom Iterator method, `anyBlockIterator`, from `ScaleReverseTest.java` and updated the test assertions to use any instance of the Iterator class. This simplifies the testing setup, reduces redundancy and improves the readability of the tests. Also, removed the redundant Maven Test command in the GitHub workflow file.
