Steps to reproduce

1. Create a document type T
2. Create a folder F
3. Create a document D of type T inside F
4. Edit document D and publish again
   1. A new version of document D is created
5. Edit folder F and add restriction to the file types, so that it should contain only documents of type "Basic Document". Confirm.
   1. Assert document D is converted to type "Basic Document" (it loses all fields added or metadata sets added to type T)
6. Revert document D to previous version.

Expected behavior
Previous version of document D will obey the folder restriction and will be converted to the new file type.
Actual behavior
Document D will be reverted to the previous version with file type T.
