Skopeo delete image failing - attempts deleting manifest before tag

Running command `skopeo delete docker://gcr.io//: --creds `.

Fails with: `{"errors":[{"code":"GOOGLE_MANIFEST_DANGLING_TAG","message":"Manifest is still referenced by tag: "}]} (400 Bad Request)" `

It looks like it is attempting to delete the manifest first before removing the tags but this is not allowed by GCR. This may cause issues where it would require deleting all tags before a manifest can be removed. An associated issue with details can be found here: https://github.com/genuinetools/reg/issues/136.

Start by reproducing the documented `skopeo delete docker://gcr.io//: --creds ` command and compare its 400 response with the linked `genuinetools/reg#136` issue. Done means the delete operation no longer attempts to remove a manifest while its tag still references it, or the required deletion behavior is documented.
