get_ag_barcode_details pulls the kit email, not the participant email

[wasade]

A more accurate base query can be formed with:

select * 
    from ag.source_barcodes_surveys 
        join ag.ag_login_surveys using (survey_id) 
        join ag.ag_consent using (ag_login_id, participant_name) 
where barcode='foo';

This query needs to be expanded to touch ag_kit and ag_login to recreate the type of result from get_ag_barcode_details
