When querying the list of packages maintained by people, also query dist-git itself
    
    So far we only relied on the pagure_bz.json file to tell us what
    someone was involved with. However, if someone set their watch
    status to "unwatch" on a package, that package will not show up
    in pagure_bz.json.
    So we'll now be querying both that file and dist-git itelf directly.
