Outdated gets confused by registry with host:port

[mstarostik]

An image like gitlab.example.com:5050/group/name:tag gets incorrectly reported as:

index.docker.io/library/gitlab.example.com 5050/group/name:tag Unable to get image data

And the current tag can't be fetched

[mstarostik]

I also see a number of these:

index.docker.io/library/sha256 766a9e7e5d31d469973555115fda6e3a56e7c963b3f335e... Unable to get image data

Where an @sha256:... spec is used. Here there is no trace left of the actual image name.
