Changing from k8s.autoscaling.v2beta1.HorizontalPodAutoscaler to k8s.autoscaling.v2beta2.HorizontalPodAutoscaler fails the first time every time

[nesl247]

Problem description

We have many projects using k8s.autoscaling.v2beta1.HorizontalPodAutoscaler. When we updated them to use k8s.autoscaling.v2beta2.HorizontalPodAutoscaler, pulumi did not do a replace. Instead, it does an apiVersion update.

Unfortunately, the first time it tries to do this fails every time.

This could be a result of #991

Need more investigation to see if these apiVersions are incompatible and should not be aliased.
