    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
