Steps to reproduce:
- Create a task (I'll call this task 1)
- Create another task (task 2)
- Go to task 2, and go to Edit Related Tasks -> Close as Duplicate
- Select task 1 and click Merge Into Selected Task
- Repeat steps 3 and 4
Expected behavior:
A user could not close a task as a duplicate multiple times, especially onto the same task
Actual behavior:
The task is closed as a duplicate multiple times
