Updated to `correct_inputs_count` as well as `partial_inputs_count` to avoid having len() in the template. The same could probably be applied to some of the `survey_question._prepare_statistics()` badge values of "Answered" and "Skipped" depending on how the fix for the counting of skipped choice questions is done + for how an "Incorrect" badge is added in (not done as part of this task since requires more changes than expected to be done cleanly).
