Fix BTR when NVidia Reflex is enabled (!71)

- Before `Application.targetFrameRate` is used in the BTR code, set it to 60. Then set it back afterwards
- Remove an unnecessary error from BTRExtractPassengersPatch, not actually an error state

All credit goes to Ngst for figuring out that NVidia Reflex was causing the BTR issues
