[CardDB] Clear CardInfo relations before deferred deletion (#7615)

Browse source 
removeCard() and swapInDatabaseData() schedule CardRelation deletion with deleteLater(), but the owning CardInfo could outlive them through an external shared pointer and kept returning the freed pointers from getAllRelatedCards(). Add CardInfo::clearDirectRelations() and call it after scheduling deletion so the UI can no longer dereference dangling relations.
