Subject: OTR: Fix onContactStatusChanged & dont archive OTR

- Fix session handling on contact status change: Do not reset
  potentially active sessions; check peer's OTR-resource on disconnect
- use no-permanent-store hint instead of no-store to ensure
  finished messages are delivered to offline/disconnected clients
- add no-permanent-store to ask compliant servers not to archive
  OTR messages
