Correct _test_delete_ports_by_device_id_second_call_failure

Currently the test assumes delete_ports_by_device_id deletes ports in
the order they were created but nothing ensures it. This change
updates _test_delete_ports_by_device_id_second_call_failure to avoid
such (incorrect) assumption. The assumption is in general broken in
daughter change which adds a unique constraint on Port table.
