The plug was attempting to register a before_send callback after
blocking a banned IP and sending a 403 response. This caused
Plug.Conn.AlreadySentError in production.
Fixed by checking conn.halted before attempting to register the
404 tracking callback. If the request was already blocked and sent,
we skip the callback registration.
Also updated the test to verify proper behavior without the
workaround for AlreadySentError.
