ApiPurge: Set the triggering user for the LinksUpdate

Even if the API call was done anonymously, we still have the IP
address to set as a triggering user. This is needed in the EventBus
since the LinksUpdate job triggers a page-properties-change event
and we need information about the performer for each page-related
event.
