Allow templates without alerts (#13150)

Browse Source 
The confirmation page template system allows templates to have alerts,
but it throws an uncaught Promise rejection if a template has no
alerts. This is the unintended side-effect of input validation.

The `getTemplateAlerts` function was updated to always return an array.
The one callsite was updated to expect an empty array if there were no
alerts to render, rather than expecting `undefined`.
