When reconfiguring the branch to something not already fetched, action_pull fails with error: pathspec '<new branch name>' did not match any file(s) known to git.
It is the "git checkout" which fails like that. To solve this, try the faster "git checkout + git pull" first and only if that fails, fall back to the slow "git fetch + git checkout". In the conf.hard_reset case, do the checkout always after the git fetch.
