 Fixed issue with detection of duplicate record fields

 Duplicate record fields would not be detected when given a type
 with multiple data constructors, and the first data constructor
 had a record field r1 and any consecutive data constructors
 had multiple fields named r1.

 This fixes #9156 and was reviewed in https://phabricator.haskell.org/D87
