twitterbridge: decide new vs old by status id, not feed position

RSSHub's guid is the timeline entry's own id (a retweet's id), so ids follow
the order the account posted, while feed order and pubDate follow the
original tweet. A fresh retweet of an old post can sort to the bottom; it is
now posted, and only ids older than every known one are treated as deletion
slide-ins. !leaks sorts by id too.
