Fix pagination number found_posts

[iandunn]

After 483f34d, the wp:query-pagination-numbers block shows 10 pages when it should show 11.

I think the problem is the one described at https://codex.wordpress.org/Making_Custom_Queries_using_Offset_and_Pagination#Offset_Using_pre_get_posts, where found_posts needs to be adjusted to account for the new offset.

add_filter( 'found_posts', __NAMESPACE__ . '\foo', 1, 2 );
function foo( $found_posts, $query ) {
	$is_posts_index = is_posts_index( $query );
	
	if ( ! $is_posts_index ) {
		return $found_posts;
	}
	
	return $found_posts + 5;
}

This is blocked by #70 , though.

#70 is closed now. Is this still blocked @iandunn?

No, but it looks like the problem was also fixed by some earlier change 👍🏻
