(POOLER-191) Add checking for running instances that are not in active

This change adds detection of running instances that are in a running
queue, but have no data in a active queue for the same pool. When this
happens a machine will live forever, impacting the running count, and
preventing the machine from being killed. Without this change running
instances that are not marked as active will live forever.
