Change language for gift card "Mailed?" field

[smarziano]

On staging when we add a gift card for new sign-ups under the "Mailed?" field it says "Created!"

After adding gift card this field should say "Yes"

Updated on staging via commit fd888db

We are coming across a similar issue to #201. We are not getting the proper messages after adding a gift card to indicate that this action has been successful.

Removing "Waiting on Merge" until this issue is resolved.
