    searchController: Avoid event.set_source() API
    
    It does not make sense that the target actor is both destinatary
    and content of the events being sent, so this API call is going away.
    
    Since the event can be sent entirely unmodified (more so, it will
    become immutable/readonly in the future), avoid creating a copy
    since it does not matter sending one or other struct.
