Anomaly with YAML anchors in RNode.YNode.Decode

[monopole]

Trouble when YAML anchors in use.

See listWithAnchors test in these two test sets

• https://github.com/kubernetes-sigs/kustomize/blob/master/api/resource/factory_test.go

• https://github.com/kubernetes-sigs/kustomize/blob/master/api/internal/wrappy/factory_test.go

Hoping this goes away after we delete all the translation layers after #2506 closes.

Don't think this blocks closing #3304

kustomize still has regression processing YAML anchors:

I'm consolidating all the issues related to YAML anchors on this one: #3675. Though they don't all fail with the same error message, they seem to all be related to the switch to kyaml. If you're encountering this issue and YAML anchor support is important to you, please chime in over there.
