Finch build with multiple tags (-t) only updates the first tag when the tag already exists

[mcmathews]

Describe the bug
When running finch build specifying multiple tags for the built container (multiple -t arguments), only the first tag is updated if the tags already exist.

Steps to reproduce
The following steps demonstrate the problem.

% echo 'FROM busybox
CMD ["echo", "1"]
' > Dockerfile

% finch build . -t test:tag1 -t test:tag2 -q

% finch run test:tag1
1

% finch run test:tag2
1

% echo 'FROM busybox
CMD ["echo", "2"]
' > Dockerfile

% finch build . -t test:tag1 -t test:tag2 -q

% finch run test:tag1
2

% finch run test:tag2
1

As you can see, after the dockerfile is changed and the container is rebuilt with the same tags, the second tag isn't updated.

Expected behavior
The output of running the 2 containers that should have been built in the build step should be the same. More generally, each finch build should update ALL the tags given to the container that is built.

To help debug the issue as quickly as possible, we recommend generating a support bundle with finch support-bundle generate and attaching it to this issue. This packages all Finch-related configs and logs into one file.

Thanks for submitting the issue! I can reproduce the behaviour on my machine with both finch as well as nerdctl. Will open an issue and try submitting a fix with nerdctl.
