WP_Rewrite::page_uri_index() includes auto-drafts

[duck_]

The query results passed to get_page_hierarchy() includes auto-drafts. This means that when verbose page rules are in use there are several useless rewrite rules created:

()/trackback/?$ => index.php?pagename=$matches[1]&tb=1
()/feed/(feed|rdf|rss|rss2|atom)/?$ => index.php?pagename=$matches[1]&feed=$matches[2]
()/(feed|rdf|rss|rss2|atom)/?$ => index.php?pagename=$matches[1]&feed=$matches[2]
()/page/?([0-9]{1,})/?$ => index.php?pagename=$matches[1]&paged=$matches[2]
()/comment-page-([0-9]{1,})/?$ => index.php?pagename=$matches[1]&cpage=$matches[2]
()(/[0-9]+)?/?$ => index.php?pagename=$matches[1]&page=$matches[2]

Steps:

1. Visit add new page to create an auto-draft
2. Go to options-permalinks.php and enable a verbose structure

I *think* this query might actually scan fewer rows since it's able to use another element of the type_status_date KEY.

Should we exclude any other stati?
