Marcel Märtens 5fe7c05d9c Redefine Close behavior:
- When Participant A was closed by remote side. Then a `disconnect` on `A`
   shall return Ok() (instead of ParticipantDisconected) IF:
   A was already flushed and no data needs to be sended any more.
 so a `disconnect` doesnt differ if the other side initiated the disconnect before or not. it tries to clean things up and returns Ok(()) if both sides agree
