AttributeError: 'WikiCreateTicket' object has no attribute 'wiki_page_deleted'

I think WikiCreateTicket module should have the following methods.

wikicreateticket/__init__.py

(In [10641]) Adds wiki_page_deleted, wiki_page_version_deleted and wiki_page_renamed. AttributeError happens when deleting a wiki page without these methods (fixed #9150).
