CSV export contains unreadable Satisfaction data

Steps to reproduce

1. Enable Satisfaction for an SD project and Resolve a Request for a Survey to be sent to Reporter
2. Rate the Survey with a Five-star
3. Go to Issue Navigator and search for Satisfaction = 5
4. Edit Columns and display Satisfaction (List view only)
5. Export the result to CSV (Current fields)

Expected behavior

The Satisfaction field in the CSV file contains a readable value of 5

Actual behavior

The field contains an unreadable value e.g.:

com.atlassian.servicedesk.internal.api.customfields.feedback.RequestFeedbackCFValue@d3f24

Note

In SD 3.1 with Excel export (CSV is available in SD 3.2), the field is reported not to contain any value in the Excel file
