      Modify 2 channel circular replication testcase to use IGNORE_SERVER_IDS
      
      The 2 channel circular replication testcase uses the same server id for
      both MySQLDs on each site to avoid double application of 'reflected' events.
      
      This is not necessary with the IGNORE_SERVER_IDs CHANGE MASTER option, so
      the testcase is modified to use distinct server ids + IGNORE_SERVER_IDS.
