Bring the transclusion title back to life

At some point getTitle was changed to updateTitle but the caller was still
assuming it would return a string. Also, we removed the transclusion
dialog title message, but were still trying to use it.

Changes:
* Change the logic so we use the parent method for updateTItle correctly
* Bring the transclusion title message back
