fix(email): use the customized global email content as a starting point for per-form emails

[Benunc]

User Story

As a give admin, I want to customize the recipients to a form's email without having to copy in a customized global email so that I don't have to start from the default email content each time.

Current Behavior

If I have dozens of forms, and I've customized the email content in the global settings at Donations > Settings > Emails (tab), and I want to customize only the recipient for the New Donation notification, without changing the content at all, my current workflow is to click (on the individual form) Emails > New Donation > Customize and then scroll to the bottom and change the recipients. This would revert the email content back to the default message that ships with Give.

Expected Behavior

If I've already customized the email content in the global settings, I would expect the global settings to carry over to the individual form in question, so that I can just change out the email recipient without having to also copy in the email content from the global settings.

Possible Solution

Check for a customized email content in the global settings, and populate that in the individual form settings.

Steps to Reproduce

1. Customize the email content at Donations > Settings > Emails (tab) for the New Donation notification.
2. On an individual form, attempt to customize only the recipients for that same notification.
3. It will default to sending out the unmodified default email.
