      Setup a RS
      Reconfigure it to disallow Replication chaining. 

      cfg = rs.config()
cfg.settings.chainingAllowed = false
rs.reconfig(cfg)

      Step down the primary.
      The RS is chaining again.

      The issue can be reproduce also if the RS is started having the chainingAllowed parameter = false. The initial configuration is ok, after the StepDown the cluster is chained.

      The parameter chainingAllowed = false is not enforced after a rs.stepDown() command.

      The secondaries are chained with the old primary connecting to the new primary directly but the other secondary syncing from the old primary.
