CSV export: non answered is reported as "No"
CSV export do not differentiate between an negative answer and an absence of answer. This make it unpracticable to analyze the poll with these exported results.
Procedure to reproduce: Create a poll, add an incomplete line (some choices answered, some not answered), export as CSV
Observed: the dates/choices whose user has not answered are reported as "No"
Expected: these choices should be different than "No", for example "Not answered"
