Update clone delegation to not raise an exception if the delegator's KEL is not in local kevers
Fix event handling to walk the KEL to find an anchoring event if it exists.
These changes close #842 by allowing for a witness to return a KEL for a delegated AID without the AES couple for approved events and without the delegator's KEL.
This is the expected behavior for a witness as it should not be assumed that a witness perform watcher functionality. Any validator will have to be introduced to the delegator or OOBI with the delegator before validating the KEL of the delegate.
