Use todo!() instead of () for missing fields

Browse source 
The generated code with `()` doesn't compile in most of the cases. To signal
the developer there's something to do, fill in `todo!()`.

Because the file *missing_fields.rs* contains the string `todo!()` it needs
an exception for the test *check_todo*.
