  Log:
  SVN rev 220865 on 2011-04-19 19:26:27Z by pjd
  
  Scenario:
  - We have two nodes connected and synchronized (local counters on both sides
    are 0).
  - We take secondary down and recreate it.
  - Primary connects to it and starts synchronization (but local counters are
    still 0).
  - We switch the roles.
  - Synchronization restarts but data is synchronized now from new primary
    (because local counters are 0) that doesn't have new data yet.
  
  This fix this issue we bump local counter on primary when we discover that
  connected secondary was recreated and has no data yet.
