mod_pubsub: Move reversal of item order in <items> Examples in XEP-0060 suggest that items should be listed in chronological order, but we get them from the archive in reverse order. However when requesting specific items by id the results keep that order and we don't want to flip it again. At some point it would likely be best to use the archive API directly instead of this util.cache-compatible wrapper.
