Shourya Gautam ea8fc72570 db: backfill zero-time node expiry to NULL ... Versions before 0.28 persisted a pointer to a zero time.Time as '0001-01-01 00:00:00+00:00' in nodes.expiry rather than NULL. 0.29 reports those rows as expired. #3197 and #3199 stopped new writes; this normalises the existing rows so the column once again means "no expiry" when unset.
