Deleting a user in Settings - Users page doesn't update table "page_author"
If a user is author of page(s), he stays author even after deleting him in Settings - Users page. Problem: if we create a new user, is id is the same than the id of the deleted user. Then, the new user automatically becomes author of pages the deleted user was.
TODO: when a user is deleted, delete all lines in table page_author that contain the deleted user id OR the deleted user email address (in case of his account was not activated).
