[RBAC] Fix server error from delete capability of approvals

[AlanCoding]

SUMMARY

Now this is a skeleton that adding validation managed to dig up. Look at WorkflowApprovalAccess, it never wrote CRUD access logic... and this model doesn't have roles either.

So it deferred to BaseAccess. What does that mean? Edit / other stuff is restricted to superuser. Okay, but the view probably doesn't allow this anyway, right? Nope, it does. Didn't make sense then, still doesn't make sense. I'm just trying to fix the server error.
