stepup version create --no-editor doesn't work

Turns out that if my .git/config doesn't set `remote.origin.fetch +refs/heads/*:refs/remotes/origin/*` stepup thinks that I'm working on a local repository. 

I solution would be
`stepup version create --no-editor` always push to remote

A fallback in case you don't want to create a new version remotely would be:
`stepup version create --no-editor --local`
