[Registration] Empty course info when the name localization fails
When the user submits a registration and some of the courses receive a falsy validation result, if the course name localization fails, no course info is shown. The course's display code can be shown in that case.
{{failedCourse | localize:['name'] || failedCourse.displayCode}}
and all relevant expressions need to be converted to
{{(failedCourse | localize:['name']) || failedCourse.displayCode}}
