Service events no longer erroneously report scaling down to zero instances
In rare cases, Render would erroneously emit an Autoscaler starting to scale down to 0 instances event for services with autoscaling enabled. These events were triggered by momentary latency in scaling metrics, and they did not modify the instance count of the affected service.
This behavior is now resolved.
