Renaming file names does not check for illegal characters

How to reproduce

• In the folder component, create a folder with the filename "Du : da"
  => OK: can not be saved, error message appears
• Create a folder with the filename "Du da"
• Open rename dialog for this folder
• Rename to "Du : da", save
  => NOK: filename is not validated

Must use the same filename validation as when creating files or folders
