Summary:
Ref T4788. When closing a task as a duplicate of another task, you can only select one task, since it doesn't really make sense to merge one task into several other tasks (this operation is //possible//, but probably not what anyone ever wants to do, I think?).
Make the UI understand this: after you select a task, disable all of the "select" buttons in the UI to make this clear.
Test Plan:
- Used "Close as Duplicate", only allowed to select 1 task.
- Used other editors like "Merge Duplicates In", allowed to select lots of tasks.
