Git does not have --tags option anymore

[javierggt]

I got the following error:

git.exc.GitCommandError: Cmd('git') failed due to: exit code(128)
  cmdline: git fetch -v -- origin --tags
  stderr: 'fatal: couldn't find remote ref --tags'

and this command fails:

git fetch --tags

This happens in skare3_promote.py:85 and perhaps other places.
