[NO ISSUE][TEST] Align Poll Time in Async Tests

- user model changes: no
- storage format changes: no
- interface changes: no

Details:
- In some Jenkins runs, the async-running test fails
  due to short (10s) poll time, while the job takes
  (~16s) to finish. This change aligns the poll time
  of that test to (20s) to match the other async tests.
