Title: git-create-branch: bug fix for branch creation use HEAD instead of origin

Getting error
```
error: src refspec origin does not match any.
error: failed to push some refs to '....git'
```

if you are trying to push the current branch head to remote, the command should be:
```
git push origin HEAD:refs/heads/$branch
```
