Comment 1 for bug 619022

This case is a little more esoteric. This team had a list purged, then it was renamed. The team has the old mailing list address but the mailing list does not. This is expected. setContactAddress should not assume that it will always have an email address for a mailing list. It is okay to be None, since the deletion loop does the right thing, but the MasterStore step is not needed.
