fix(go): duplicate conversion functions when parent structs have the …

…same base name If a struct has two parent structs with the same base name (but different packages), the emitted conversion function will have the same name (`ToParentStruct` and `ToParentStruct`). Since we are not even sure that these base conversion functions are required, omit them for now and we can decide to restore them at a later stage if the use case is clearer. Fixes #2692
