This ticket is about changing export code to include the campaign and keywords in the database result instead getting them out of the legacy "data blob".

Affected repositories

• Fundraising Operation Center

Implementation notes

1. Change src/DataAccess/DonationExport/ExportQueryBuilder.php to JOIN the tracking table, adding campaign and keyword fields.
2. Create a custom export field mapper in src/DataAccess/ExportFieldMappers that returns the field names in getSQLFieldName. The implementation of getValueFromDbResult returns either an empty string (when both fields are empty) or the campaign and keyword fields joined by a slash
3. Change entry for tracking in src/DataAccess/DonationExport/DonationExportFieldCollection.php from LegacyDatabaseField to a the new field mapper class.
