Clear session links no carry-over made, at boot

Sessions from v0.2.8 and earlier were linked to the one before them by
every rollover and New session, so production threads offered "Show the
previous session" (and prompts read summaries) for sessions nothing was
carried from. A link is kept only when the session opens with a message
carried from that session.
