Issue Description

Adding an afterSave hook on the built-in _Role class causes a validation error, even if the hook is completely empty and makes no changes to the object.

The error is:

A role's name can only be set before it has been saved.

This seems to be triggered due to internal behavior when handling _Role objects during the afterSave lifecycle. This bug prevents any post-save logic from being used with _Role.

---

Steps to reproduce

1. Add this Cloud Code to Parse:

Parse.Cloud.afterSave('_Role', async (request) => {
  // no-op
});

2. Run the following in your client or console:

const role = new Parse.Role('Admin', new Parse.ACL());
await role.save(); // fails

3. Observe the validation error, even though no modification is made in the hook.

---

Actual Outcome

save() fails with the following error:

A role's name can only be set before it has been saved.

---

Expected Outcome

Saving a _Role with an empty afterSave hook should succeed, as long as the name field isn't modified.
