Posts: Non-trashed posts should take slug priority over trashed posts.

When determining a unique post slug, trashed posts are taken into account. Previously, new posts would add suffixes to their slugs (e.g. `about-2`) when a post in the trash had the desired slug (e.g. `about`). 

To avoid this behavior, when a post is trashed its slug (i.e. `post_name`) is now suffixed with `-%trashed%`. The post's pre-trash slug is stored as post meta, and if the post is restored from trash, its desired slug is reapplied. 

For existing trashed posts which don't have the `-%trashed%` suffix, the suffix is added when a post with its desired slug is created.
