Have Create Org use the account's email address that kicks the build off

[annejackson]

Use case:
I am using MetaCI's Create org page to build an org:
https://mrbelvedereci.herokuapp.com/create-org/

I want the org that is created to use my email address that is listed below for email fields such as the default user's email address that gets created (this will help ensure that error notifications and other email notifications get sent to my email when testing):
https://mrbelvedereci.herokuapp.com/accounts/email/
