revision: fix --missing=[print|allow*] for annotated tags

In 9830926c7d (rev-list: add commit object support in `--missing` option, 2023-10-27) we fixed the `--missing` option in `git rev-list` so that it works with missing commits, not just blobs/trees. Unfortunately, such a command was still failing with a "fatal: bad object <oid>" if it was passed a missing commit, blob or tree as an argument (before the rev walking even begins). This was fixed in a recent commit. That fix still doesn't work when an argument passed to the command is an annotated tag pointing to a missing commit though. In that case `git rev-list --missing=...` still errors out with a "fatal: bad object <oid>" error where <oid> is the object ID of the missing commit. Let's fix this issue, and also, while at it, let's add tests not just for annotated tags but also for regular tags and branches.
