fix: individuals request preserve values

[elasticspoon]

Fixes #4135

When individuals requests were submitted with incorrect values the error page did not preserve correct or incorrect inputs.

This was happening because the controller created a new request on error. Now the new request will be populated with the items from the failed request.

Notes

I attempted to reuse the failed request, however, that was not possible.

The form expects a FamilyRequest. The service object that deals with the request does not create a FamilyRequest, instead it reuses the family request service which does not store or create a FamilyRequest. The other option would be do a large refactoring and add additional objects such as an IndividualRequest and IndividaulRequestService.

That might be something worth doing, I chose not to just to get this bug fixed.
