After the first clone of a repository for a new job, the Git module runs 'git
tag l hudson*' to look for existing tags. Since there are none yet the command
fails and exits with a non-zero return code (1). At this point the job fails
rather than running the job and creating a tag for the next poll cycle. Manually
creating a tag enabled the next poll to succeed and kick off the job.
