Image delete has no function

[typoworx-de]

I'm using current :latest release with REGISTRY_ALLOW_DELETE=true but hitting delete button obviously has no function as the image will not disappear from UI.

Checking registry using curl:
curl https://my-private-registry.docker:5000/v2/_catalog

only lists the image not deleted, so delete seems to work at registry but not for UI (caching?!).

seems there is already an issue for that #44
