"sticky" shouldn't be added to paged posts

[iandstewart]

Sticky posts are routinely styled by WordPress themers with the "sticky" class added to get_post_class if a post is sticky and it's in the blog loop (is_home). But, currently, that means paged posts are also getting "sticky" styles and appearing like "sticky" posts out of joint.

Attached is a diff checking to see if a post is paged before adding sticky to the array of post classes

Stickies are only fetched in WP_Query::get_posts() if page <= 1, so I think this is safe.

That line was last changed when #7712 introduced is_home(). !is_paged() seems like a good addition.

(In [15088]) Don't add sticky class if is_paged(). Props iandstewart. fixes #13666
