fix(attributes): Apply consistent scrubbing across deprecations

[mjq]

Description

Apply the same scrubbing rules across entire deprecation chains. This keeps the scrubbing behaviour predictable whether or not Relay is doing attribute rewriting. It also make semantic sense - if two attributes have identical semantic meanings, they should also have identical scrubbing rules.

PR Checklist
