 Bug 15493: Use the correct CSV profile when exporting records from the export tool

The CSV profile used is not the one the user has chosen, but the one
defined in the pref ExportWithCsvProfile.

It's caused by a wrong variable name csv_profile vs csv_profile_id

Test plan:
Define 1+ csv profiles
Set ExportWithCsvProfile with 1 of these profile
Use the export tool to export some records using a csv profile.
Without this patch, the csv profile used, will always be the one defined
in ExportWithCsvProfile.
