With T19437, the auto select service does also include the configuration of "MITK DICOM Reader v2 (classic config)". We deactivate the registration of "MITK DICOM Reader v2 (classic config)" in order to avoid the pop up selection when loading normal DICOMs.
WARNING: This change will be a breaking change for all code that uses mitk::PreferenceListReaderOptionsFunctor to use the "MITK DICOM Reader v2 (classic config)". This should be changed to ""MITK DICOM Reader v2 (autoload)".
