Gig details - can't send email referral more than once

[kkartunov]

Steps to reproduce:

1. go to https://www.topcoder.com/gigs/16341500556800013350dQL or any other gig
2. Use the form to send relerral by email
   
3. Go to another gig and try send to same email used in step 2 -> Error triggers.
   

Expected: No error modal. Referral email sent. No count for the $10 award as the recipient was already referred.
