docs: Purges a conneciton from the tracker. This is invoked when an error is detected on
  a connection and we do not want any further conversations to attempt to use it.
  
  @param connection The connection to purge
  @param notifyPeer Should we send notification to the connections peer that the purge
  is taking place?
