Offer better test logging

The tests currently offer bad logging messages. Each test should add a rule like

final Logger logger =
LoggerFactory.getLogger(PersistenceTest.class);

@Rule
public TestWatcher watchman = new TestWatcher() {
/**

• Invoked when a test is about to start
  */
  @Override
  protected void starting(Description description) {
  logger.info("{} being run...", description.getMethodName());
  }
  };
