Create/alter previous versions if version changes
Until now every time a terminology has been changed for any reason (new version, new MaLaC-CT build, etc.) a new previous version of the terminology has been created. However, a new previous version shall only be created if the version of the terminology has been changed - main reason for this is to make it easier and more transparent for customers to access outdated versions and to save storage space.
