using --pull doesn't do what one would expect - if the repo exists locally, it doesn't pull the branches/tags that are needed

For each repo whereby the stack has been updated, I have to go into it and git fetch -a origin then continue
e.g.:

# laconic-so --stack fixturenet-payments setup-repositories --pull
