The email script was failing validation because of missing parameters in scripts.email.do_task_validate_only.

I added a test in tests.test_email_script to make sure we get the default email_address.
I also found and fixed a bug in workflow_service.populate_form_with_random_data where we would overwrite default_values with random text because of a missing continue.
(We don't want to continue if we have repeating fields though.)
