fix: Email sent via ACE cannot use Braze as a mail-delivery backend unless

a valid LMS user ID is supplied. If Braze cannot be used, AWS SES is used
instead. However, sometimes the SES score can prevent email from being delivered.
Make a best effort in every case to obtain a user ID and send it along with
the email to be sent by ACE and Braze.
