 Handle DuplicateRecordFields correctly in filterImports (fixes #14487)

 filterImports needed a small adjustment to correctly handle record field
 definitions arising from modules with DuplicateRecordFields enabled.

 Previously hiding fields was not possible with DuplicateRecordFields
 enabled.

 Test Plan: new test rename/should_compile/T14487
