Default value for `tag` does not work

[sja]

My configuration contains this:

        # Does not work
        tag: 'myRepoOne'
        refs:
          - 'refs/heads/feature_(.*)'

But that does not use the tag on creating jobs. I had to put a tag on the ref config:

        # Works
        tag: 'myRepoOne'
        refs:
          - 'refs/heads/feature_(.*)'
              'tag': 'myRepoOne'
