Git/SVN: die when there is no commit metadata

When passing a bad --trunk option to `git svn clone`, like for example the
same URL that we are cloning:

  C:\Windows\system32>git svn clone
  https://mycompany.svn.beanstalkapp.com/myproject --no-metadata -A
  c:\temp\svn_to_git_users.txt
  --trunk=https://mycompany.svn.beanstalkapp.com/myproject
  --tags=https://mycompany.svn.beanstalkapp.com/myproject/tags
  --branches=https://mycompany.svn.beanstalkapp.com/myproject/branches
  c:\code\Git_myproject

One gets an "Use of uninitialized value $u in substitution (s///)" error:

  [...]

Let's fix that by just die()ing when we have an uninitialized value because we
cannot get commit metadata from a ref.
