Fix: Update test expectation for validation call count

Test was expecting 2 validation calls but actually getting 3.
With the #1050 fix, validation now runs three times:
1. During synchronous registration (useState paused)
2. During normal registration (useEffect)
3. After initial values are applied

Updated test expectations and comment to reflect the actual behavior.
