interfaceOperDown events are sent every time a node with down interfaces is rescanned.

      Description

      Since our upgrade from opennms-1.8.14-1 to opennms-1.8.15-1, rescans of machines with down interfaces generate interfaceOperDown alarms, even if the interface already existed and was down before the rescan.
      This only affects snmpinterfacepoller polled interfaces.
      Each machine may have many down interfaces, and rescans are run by default every day, so this can generate a large number of false alarms.

      I can reliably reproduce this using send-event.pl with uei.opennms.org/internal/capsd/forceRescan
      This does not appear to affect all machines with down interfaces, but the ones it does affect it affects reliably. I will investigate this further.

      Given that this wasn't an issue in 1.8.14, this seems to be a newly introduced problem.
