/**
 * What this is aimed to test:
 *
 * EXPIRE_NEVER annotations should be expired when a page is removed from the
 * database.
 * If the annotation is a page annotation this will happen when the page is
 * expired, namely when the page has no visits and is not bookmarked.
 * Otherwise if it's an item annotation the annotation will be expired when
 * the item is removed, thus expiration won't handle this case at all.
