There are multiple problems with it:
* the --reviewers options works differently, as it should be added only
once and then listed the emails
* in case of dummy contacts or not registered contacts the git-review
command fails
Since we have already a script [1] to add reviewers to *every* open
patch, it is easier to run that *after* we finished the bulk uploading
of patches.
