Error message (caused by uppercase letter in name argument to "docker tag") does not mention casing

[teetotum]

When I tried to use docker tag to specify my registry and image name, I got the following error:

docker tag 08245 registry.example.org/foo/screenApp
Error parsing reference: "registry.example.org/foo/screenApp" is not a valid repository/tag

I figured out what the problem was (uppercase letter in name component) and saw that others had the same problem.

Expected result for the error situation is that the error message mentions the wrongful presence of uppercase letters.

@vdemeester Looks like the error message is now correct. It says: invalid reference format: repository name must be lowercase

Yay 🎉
