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). Signed-off-by: Miloslav Trmač <mitr@redhat.com> Closes: #1176 Approved by: rhatdan
