Ensure resource defaulting is always done regardless of ref type.

[wlynch]

Changes

Previously we were only setting defaults for k8s API based resources. This change ensures defaulting is done after we've extracted the spec, making it agnostic to the resolver type.

This isn't a change in behavior, this just ensures that we're applying defaults consistently.
