Try this. Open Nova launcher settings - scroll all the way down and open 'advanced' - screen lock method - select 'Timeout'. This should uncheck Nova as device administrator.

If you want to deactivate Nova make sure to set the stock launcher as default first.

>> If you use android 7+ you must hold tap on app and leave it Sleep. After you could disable it from administrators and uninstall it.
