Motivation
https://github.com/spearbit-audits/alchemy-nov-review/issues/34
Session key permissions rotation does not check that the key is registered prior to rotation. This allows key rotation to override existing permissions, and to do pointless key rotations into the same key.
Solution
Add a check asserting that the new key to rotate into is not already registered.
Add a test asserting a revert in the case where the key to rotate into is the same or already registered.
