[THRIFT-3108] Defaulted struct parameters on a service generates invalid Haskell.

Description

If we have a service definition that looks something like:

struct ServiceRequest {
  1: optional bool shouldWork;
}

service MyService{
  void myService(1:ServiceRequest request = {});
}

The code generation relating to the service call includes an invocation like this:

... = default_ServiceRequest{}

Which is invalid as empty record updates are not allowed.
