Sanitize values for CSV.

[Ruk33]

Fixes

Issue Number: #7692

What is the current behavior?

When exporting to CSV, no sanitization is being performed, thus,
the export may be incorrect if any of the values use a comma
or ".

What is the new behavior?

All values are enclosed in " and extra " are escaped.
