stringutil: edit comment to reflect actual data type name In development the data type used to hold an email/name pair was called a "mailmaptup" since it was implemented as a namedtuple. The implementation has since been changed to use an @attr.s decorated class named mailmapping. This commit changes a comment to reflect this change.
