Reverse current sort order of unknown watch dates

Currently if you sort by last watched date descending to see your most recently watched items, items with unknown watch date are at the top of the list. I think it would make more sense to treat unknown watch dates as an old watch date rather than a new one. My reasoning is that if you don’t remember when you watched it, it probably wasn’t recent - so better to treat it as an old entry rather than a new one. So the sequential order would be unknown watch date (perhaps sub-sorted by release date) < oldest watch date < newest watch date.
