Folders can be renamed from one name to another.
A new folder metadata transaction is created when a user wants to rename an existing folder.
The new folder metadata transaction reuses the existing folder’s
Folder-Idand copies all of it’s old metadata values, but the folder’s
namefield in its Data JSON must be updated to the new folder name.
For private folders, new ciphers are generated for this new metadata transaction.
Folders must not be allowed to be renamed to the name of another folder with that same name in that same folder.
