Fix #2673

How to test this PR?

Create different tags for the same image and try to delete them using podman-desktop ui. The selected tag should be deleted, not all the tags of the same image.

I think it's missing test where images have same id but different tags, etc

[dgolovin]

@benoitf I will do that, but that is rather an integration test that should be executed with real podman. I can mock it, but that would not be a correct validation, because I can mock it to work, but it does not mean it works with actual podman.

All new code seems to be covered with existing tests.

nice work 👍

[benoitf]

so I was testing again and noticed that there is one usecase where we have a regression

I have some leftover images and I was no longer able to remove these images

I've checked with the main branch and it's working so it's related to this PR

it's for images without a tag

for example do

podman pull quay.io/podman/hello
podman untag quay.io/podman/hello

then you see an image like

and trying to remove it leads to

then try to remove this image

[dgolovin]

Good catch. I remember I've seen images like this, but did not pay enough attention to it :(.

[benoitf]

now it works as expected 👍

maybe add a test for the <none> usecase as it's not covered by a test, so we might forget about it later
