DocumentMovedListener blocks renaming because of too long field (255)

With a page that has a fullname very close to 255 characters (but under), the DocumentMovedListener will fail and block the rename because the information stored in the notifications data will be over to 255 (because the wiki name is added).

This is also breaking the Nested Pages Migrator

Here is the exception.
