Don't format to string and re-parse a DockerReference()
We already have a c/image/docker/reference.Named; no need to
round-trip it through a string. This also eliminates the theoretical
parsing failure, and the unchecked .(reference.Named) cast.
Also add a check for DockerReference() == nil to be extra paranoid,
although that should never happen.
Should not change behavior (but does not add unit tests).
