The surveys should be more lenient and this field should be made optional to avoid everyone having to work around the problem.
== Notes
* Surveys can be defined without descriptions (see [[ https://gerrit.wikimedia.org/g/mediawiki/extensions/QuickSurveys/+/d59a84f0ad1d872ffcf304b5393c0840e0ab43d3/includes/SurveyFactory.php#165 | here ]] and [[ https://gerrit.wikimedia.org/g/mediawiki/extensions/QuickSurveys/+/d59a84f0ad1d872ffcf304b5393c0840e0ab43d3/includes/SurveyFactory.php#197 | here ]])
