Docker's image pull syntax repo/image:tag@sha should be supported as well for compatibility reasons - despite its ambiguity.
I came across this problem using skaffold and CRI-O.

The current code already handles pulling such image references by digest properly. However a dockerReference construction explicitly fails when both tag and digest are specified.

Refers to containers#783.

Changes:
- Move the code that returns an error when both tag and digest are
  present from `newReference` to `reference.newImageDestination`
  allowing pulls but no pushes.
- Use digest instead of tag as `DockerReferenceIdentity` or rather
  for policy matching.
- Adjusted tests.
