This PR addresses an issue where our criteria matching logic was not accounting for RAS readers that had logged out. We address this by also checking the RAS authenticated flag.

How to test the changes in this Pull Request:

1. Set up two custom campaign prompts, one for logged in users and one for logged out users
2. Add the prompt to any page or post
3. As a reader, login and view the page or post where the prompt is set
4. Verify the logged in prompt is visible
5. Go to my account and log out
6. Once again visit the prompt page
7. On trunk the logged in prompt will still be present, on this branch the logged out prompt will be present.

It works as described in testing instructions but I'll defer the review to @miguelpeixe and @dkoo .

Technically, the segment is not for "logged out" readers, is for "readers that don't have an account"... So if they just logged but we know they have an account, should we display that prompt?

Just FYI @leogermani, there is discussion in the Asana task about this: https://app.asana.com/0/1208604368072430/1208670219439751/f
