[FIX] survey: apply conditional configuration to free text section

As section with description are now considered as potential questions to
display, the method to get the next question to display needs to check if
the next section should be displayed or not, depending on conditional
configuration and user inputs.

For page_per_question and page_per_section layout, the following rule now
applies:

If the section is empty (has no sub-questions):
    Show it if section has description, else skip it. (in both layout)
If the section has sub-questions:
    If a least one sub-question is active:
        In page per section: show it.
        In page per question: show if section has description, else skip it.
    If no active sub-question: Hide it.

Apply also empty section rules to non conditional survey :
If a section is empty (no description and no active questions inside), the section
should not be displayed.
