Audit records name accounts in full, and holds by name

An account's or mailing list's name is only its local part, so the log
said "Account ken.gosling" where two domains could each have one; it
now says [email protected]. A change to a legal hold was
recorded under its id; the hold's current state is now read first, so
the record carries its case name and each change reads before/after.
