Thanks for your review, [~elgoiri].
If not changing the order, expired records keep existing in the
cache({{result}} at {{CachedRecordStore#118}}) after deleting them from State
Store by {{overrideExpiredRecords()}}. Then, they are deleted from the cache in
the next loadCache.
If changing the order, they are deleted from both State Store and the cache at
the same loadCache. I think changing the order is more accurate.
Indeed, we should move the timestamp too. Uploaded 006.patch addressing it.
