…e type and labels (#6428) This PR extends the suite test `test_classifier_on_unit_test_data` to test that `y` of object or str dtype `y` leads to correct labels on `predict` outputs. Covers second bug in #6427, namely the example returning integer labels instead of string labels - but does not fix the bug. It is hence expected that the test will detect bug #6427. Depends on the following PR which fix newly covered bugs: * #6430 * #6432
