[FIX] survey: correctly handle "free text sections" in surveys and sessions

We now have a way to display "free text sections" during the survey flow.
(Since 5b74f54396f6cf8986494e4632d0ea1b9940619b )

However, the behavior during survey sessions was not optimal:
- Attendees could click on "submit" and it would raise an error
- The section description was not displayed on the host screen
- The section description was never the "current question" of the session of it
  was the first item of the question_and_page_ids

This commit fixes all those points to have a nice session flow.

While the host is explaining the section description to the attendees, they get
a waiting message on their screen.

In addition, we fixed the display to avoid showing pages that lack a
description, and we reworked the '_get_pages_or_questions' method to have more
meaningful and readable cases for every layouts.
