fix: excludeExtraneousValues doesn't work with arrays

[kirill-kostenetskyi]

let results: TypedModel[] = plainToClass(TypedModel, res, { excludeExtraneousValues: true });

Once res is array of items, the results array will contains item which is not exist in model schema. Is this correct behavior?
