fix: same vcs info appened twice when running jf rt build-add-git command twice

It turns out to be practical if you can perform issue collection
multiple times using different configurations (different regexes).
However, in this case (and in any case) you do not want to see the vcs
information duplicated. This is fixed hereby.
