A customer asked me about IndexOutOfRangeException occurred at Adaptive Performance from this ticket.

Research result, I think Adaptive Performance has a bug.

When SetRefreshRateByIndexInternal(int index) API in SamsungGameSDKAdaptivePerformanceSubsystem.cs called occurs a exception at Adaptive Performance 2.0.1. The exception occurs when the app is first running only. it is running normally from second. (Adaptive Performance 2.1.0 has a same problem too.)

1. I think it is wrong that a logic operator of the first if statement at "SetRefreshRateByIndexInternal(int index)". I think '&&-AND logic operator' is right instead of '||-OR logic operator'.

2. SupportedRefreshRates value is changing at UpdateRefreshRateInfo() API. But because of not refreshing m_DefaultRefreshRateIndex value, I think it is occurring that exception.

-------------------------------------

Step to reproduce:
1. Create a new project
2. Package Manager > Install 'Adaptive Performance' Package.
3. Scalar Settings:
- selects 'Adaptive Framerate' and 'Adaptive LOD' only two
4. VRR Settings
- checks' Automatic VRR'
5. builds app (apk) and install to Android device.
6. runs the app.

--> 'IndexOutOfRangeException' occurs (only first running after install)

Test Device:
Samsung Galaxy Fold 2 (Android 10)

Actual Result:
The exception occurs when the app is first running only. it is running normally from second.

Expected Result:
App runs normally without a exception always.

Reproducible in:
2019.4.6f1, 2019.4.16f1 with Package Version 2.0.1 (or 2.1.0)
