Registration reminders also go to Waitlisted people

Problem/Motivation

The event registration reminders go to all registered people at the moment, regardless of whether they are waitlisted or not

Proposed resolution

In file recurring_events/modules/recurring_events_registration/modules/recurring_events_reminders/recurring_events_reminders.module line: 156.

Change: $registrants = $registration_creation_service->retrieveRegisteredParties();

To: $registrants = $registration_creation_service->retrieveRegisteredParties(TRUE, FALSE);

Background info:

From recurring_events/modules/recurring_events_registration/src/RegistrationCreationService.php line 170 onwards
