Add a catz system test check for [GL #3911]

The trick is to configure a duplicate zone, which comes after the
catalog zone, where the duplicate zone is an existing member zone.

In that scenario, all the zones which come before the "faulty" zone
in the configuration file will fail to be reverted to the previous
version of the view after a reconfiguration error, and in this
particular case that will result in an assertion failure when the
catalog zone update is initiated, because it will be still tied to
the new version of the view, which was dismissed.
