An auditor from our Code4rena audit correctly identified that a call to
removeOwnerAtIndex
could be replayed on another chain but might remove a different owner if the owner indexes don't match cross-chain. Since this method is one of the one's that is allowed to be cross-chain repayable, this could lead to a malicious actor removing an owner that shouldn't be removed.This PR adds the owner bytes to the
removeOwnerAtIndex
call so that the removal explicitly targets an index and an owner.
