heartbeater: slight fixes to backoff behavior

1. There was an off-by-one error when deciding how many failed heartbeats
   should lead to back off.
2. We only reset the connection to the master when transitioning to back off
   behavior, but I think the original intent was to reset it on every failed
   heartbeat thereafter.

These changes shouldn't have any real impact, but I think they make the back
off behavior more intuitive.
