TestAdlContractRenameLive.testRenameFileUnderFile raises an AccessControlException when you try to rename something under a file.
Failure is a good outcome, though rename() normally likes to fail silently with an error code of "false" in such a situation
- catch the specific exception, look for the text "Forbidden. Parent path is not a folder." and downgrade to a fail.
- declare this is a valid outcome, override the test case to expect it.
