Bug 27569: Fix CSV export for biblio frameworks

The CSV import of the biblio frameworks is broken.
A change in LibreOffice resulted in CSV not formatted how the
C4::ImportExportFramework code is expected.
This code is quite broken, it expects all the CSV cells to be quoted.

The "add tests" patch shows the different between what we expected
before this patch, and what is the new version generated by LibreOffice.

Test plan:
Export a biblio framework in CSV
Open it with LibreOffice and save it undef a different name
Create a new biblio framework and use the new file to construct it
Compare the 2 frameworks and make sure they are identical
