[IMP] survey: save questions on time limit reached

Purpose
=======

If the timer goes to 00:00, the form is automatically submitted but the answers
are not saved. The form should be submitted, validation should filter out
invalid answers to avoid showing validation errors on the form, and save
answers.
If the answer is not in the correct format : skip the question
If the answer is required but there is no answer : skip the question

This way, we can still compute score.

Specifications
==============

This commit removes the invalid answers from the question to save, only if the
timer is not over, to be able to compute score on not finished survey.

In order to avoid being able to submit answers when the survey is marked as
done, a check was added to return an error for that use case.

Also, to avoid frontend timer hacking, an extra buffer of 10 seconds has been
added. If the time limit is reached and the submit occurs 10 seconds after the
maximum stop time (start time + time limit), no answer can be submitted.
