Exclude unpublished or not accessible translations

I suggest to check only the access, there could be websites where unpublished content is accessible for anonymous. Additionally, in the near future we can support other roles scan (e.g., for intranets with authenticated users), that way the code will be compatible.

Ready to review

I have review the code and it looks great. I added a suggestion in the code.
Thanks your, Edu.
