Title: Tags: teach git_tag_list not to include the 'refs/tags/' prefix

Since quite a while now, `git_branch_foreach` has learnt to list branches
without the `refs/heads/` or `refs/remotes/` prefixes.
This patch teaches `git_tag_list` to do the same for listing tags (i.e. omit the leading `refs/tags/`)
