8. net: always complete all initial private broadcast connections

   Make sure we send out all three connections when intiating a private broadcast.
   
   Use MarkResolved instead of Remove to mark a tx as having been received back or mempool-conflicted.
   Prevent additional stale retry connections by tracking disconnects and explicitly granting new connections with TryGrantRetry.
