Bug 37606: Fix framework export module to escape double quotes

When exporting a framework as csv, the exporter does not check the presence of double quote in the fields. Hence, if there is one double quote, the csv is broken.

TEST PLAN:
1 - Change a framework to add a field containing double quote in name
2 - Export it in csv
3 - Create a new framework
4 - Import the csv in the new framework -> every fields after the one
containing double quotes should be broke. Every other fields should have
no subfield
5 - APPLY PATCH
6 - Repeat 2-5 -> everything should be correctly exported
