ROOT_NAME: "<root>" = "<root>"

Artificial placeholder for the root folder. While in production setups, it is expected, that a link to folders and especially the root-folder is not allowed (for link insertion scenarios such as drag and drop), we should handle such empty name in same way.

There is a known issue for CoreMedia CMS with ID CMS-19873, that handling for this corner case should be enhanced.

This placeholder is not meant to be used for ContentLinkView. An alternative display should be added as part of CMS-19873.
