Search AG_Handout_kits for kit_id and barcode

Now that we are doing handout kits if a participant losses credentials sql is currently the only way to retrieve them. This change addes ag_handout_kits to the search page.  
If a kit_id or barcode is not found in the normal tables than ag_handout_kits is searched. 

barcodes to test with 
000000001 - normal results
000015537 - ag_handout_kit results with one barcode in the kit
000015522 - ag_handout_kit with 5 barcodes in the kit
010000000 - no results found
