Notify listeners that vcard has changed.
This can trigger an add, change or removal event depending on whether the change causes the contact to start matching, no longer match, or stay matching the query specified by this. This method should be preferred over notify_update when the native representation of a contact is a vCard.
The important difference between this method and notify_update and notify_update_vcard is that it doesn't match the contact against the book view query to see if it should be included, it assumes that this has been done and the contact is known to exist in the view.
