test app: Improve status and error handling a bit

- Reset "running" check box if an error occurs
- Add check box to manually reset position source's error code, as error
  is not emitted with NoError
- There is no need to handle the "OK" case in errorChanged, as the
  corresponding signal will not be emitted for NoError
