Subject: [PATCH] Handle case where cards are imported into a collection with a
 newer start

https://forums.ankiweb.net/t/bug-report-when-the-original-due-is-less-than-0-the-due-will-be-weird-when-empty-the-filter-deck/31279

The 0 day case isn't fixed by this, but I don't think we can fix that
with the current schema.
