[FIX] website_blog: make latest posts snippet multi-website aware

The snippet was using the posts of all websites and blog post creation
was suggesting all blogs. Now:

- On blog post creation only suggest the blogs of the current website
- In latest posts option, only suggest blogs of the current website
- In any case, latest posts only displays posts of the current website
