Stop ignoring id fields for sub-schemas

When generating types, any field with name "id" was being skipped. The intention
here was to skip the "id" field of the embedded types.Resource struct. A type
will have an embedded types.Resource struct when the hasGet function returns
true. Therefore, this hasGet function is also used to skip the id fields as
desired.
