Title: fix epub_cover_item search

In EPUB 3, the item element has properties, not property.
http://idpf.org/epub/30/spec/epub30-publications.html#sec-item-elem

I'm not sure whether property is used or not, so I just add "item [properties = #{cover_id}]", not replace "item [property = #{cover_id}]".
