Force WithDefault not to be an optional value

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.
