Restored Post may steal slug to published Post

[ziodave]

Steps to reproduce:

1. Create a Post 1 with title "Post",
2. Assign the slug 'post' to Post 1,
3. Publish Post 1,
4. Unpublish Post 1 by setting it as 'Draft', then Update,
5. After Update, Trash Post 1,
6. Repeat 1-5 for Post 2,
7. Create a Post 3 with title "Post",
8. Assign the slug 'post' to Post 3,
9. Publish Post 3,
10. Now restore Post 2,
11. Open/Reload the edit screen for Post 3,
12. It'll show 'post-2' as slug,
13. Saving/Updating Post 3 will change the slug from 'post' to 'post-2'.

Probably the following functions participate in the issue:

• wp_add_trashed_suffix_to_post_name_for_post, which is checking for

if ( '__trashed' === substr( $post->post_name, -9 ) ) {

while Post 2 has post__trashed-2 as post name

• wp_unique_post_slug, which is not checking the uniqueness of the slug if the post is draft.
