pstats: Start new session if client disconnects before sending data

Browse Source 
This provides a better UX; if the client disconnects after the graphs open, it's quite obvious that there's still a PStats session open, but otherwise it's not obvious (and a little annoying) if you have to realize that PStats is no longer listening and you have to start a new session.
