commit fe4e478e95a3474241a5d7fea594302a3a5a52df

fix expiration completion after external expunge
when the expiration is interrupted, but an external expunge removes the
near-side message before we resume, we would just drop the transaction,
resulting in an "unmarked" orphan.
a corner case is an expiration that finishes, but initially isn't
expunged (probably due to an interruption), followed by an unexpiration
that gets interrupted, and the message being expunged externally
(because it's still marked as deleted). we obviously can't complete
that transaction without re-propagating the message, so effectively
cancel it instead.
