Cannot do a head request for private registry #1525
Description
Describe the bug
I am having the exact same issue as described and discussed in #715, with the latest version of the image and the latest registry:2 image.
My registry is located at docker-registry.sub.domain.nl, image names are single part, so docker-registry.sub.domain.nl/imagename:latest.
Watchtower tries HEAD /v2/library/imagename/manifests/latest. This fails, after which it "falls back to regular pull" and requests HEAD /v2/imagename/manifests/latest, which succeeds.
Steps to reproduce
Have watchtower try to pull an image from a private registry.
Expected behavior
HEAD /v2/imagename/manifests/latest -> no unnecessary pulls

Environment
