Describe the bug

When a grader upducks a post, it will say that A member of the teaching staff upducked the post, but on refresh, the text does not appear anymore.

Expected behavior

What happens on an initial upduck should be displayed to all users, and graders I believe are suppose to be part of upducks.
Cypress tests would also need to be modified to use grader instead of a full-access grader.

To Reproduce
Steps to reproduce the behavior:

1. login as grader
2. upduck post
3. refresh
4. See error

Configuration

• OS: [e.g. Windows, Linux, ...]
• Browser [e.g. Chrome, Safari]
