fix: Use lazy type to specialize `Edge`/`Connection`

[bellini666]

Use a lazy type to properly resolve and specialize the Edge/Connection types that are created from the model.

The reason we are using a subclass of LazyType is because the original one expects a path to be passed to be used to import it later. We don't have one here, but we do have a mapper containing all the created types that can be retrieved later.

Fix #97
