fix: end date error when certificate row not shown

[KristinAoki]

JIRA Ticket: TNL-11164

The Schedule and details page shows a permanent "You've made some changes, but there are some errors". Not sure what the issue is, but the old experience does not have the same issue.

The validator for the Schedule and details page checks if the course end date is after the certificate available date. There is a default certificate available date, but is not shown to users unless the certificate row is displayed. The error message is only shown in the certificate row, so the user is notified of the error in the parent alert but not the details of the error. Now the validator only checks for the compatibility of the end date and certificate available date when the certificate row is displayed.

Testing

1. Navigate to the Schedule and details page.
2. Fill out the course end date.
3. Alert warning at the bottom of the screen should say that changes have been made and allow you to save.
4. Enable the WaffleSwitch certificates.auto_certificate_generation.
5. Reload the Schedule and details page.
6. Certificate available row should be visible.
7. Fill out the course end date with a date after the certificate available date.
8. Error should appear in the certificate row.
9. Alert warning at the bottom of the screen should say that changes have been made with errors and saving is disabled.
