Summary: `WithDefault` appears not to be required to be prefixed with `?` because it's option value per se. Fixed tests, removed `?` where needed, updated snapshots and review them. Added mechanism fro throwing error when `?WithDefault` found. Add tests for it. Reviewed By: rubennorte Differential Revision: D16048463 fbshipit-source-id: f55ed7454aacf0b8c42944a9b5c1037ad1b360fe
