[IMP] website_slides_survey: keep challenge category updated

Purpose of this commit is to ensure challenge linked to surveys linked to
slides have ``slides`` category, while challenge linked to surveys not
linked to slides (if changing survey_id for example) have ``certification``
category.

With this patch challenges are correctly categorized, allowing to accurately
filter them based on their category.
