KFileItemModel: DetailsModeSettings::directorySizeCount forces m_sortDirsFirst

Before this patch when !m_sortDirsFirst and DetailsModeSettings::directorySizeCount() == true, the ordering of folders before files would be affected by the sortOrder. I.e descending order would put the folders after the files.
