Ensure setRequestedOrientation is called when unfolding the device

Browse Source 
- In RotationHelper, mLastActivityFlags defaults to -1, which is the same value as SCREEN_ORIENTATION_UNSPECIFIED. When the screen is folded, a new instance of RotationHelper is created, which attempts to reset setRequestedOrientation to SCREEN_ORIENTATION_UNSPECIFIED. But SCREEN_ORIENTATION_UNSPECIFIED is equal to mLastActivityFlags, and the call is skipped.
- The simpel fix is to default mLastActivityFlags to something else that is not a a valid value of setRequestedOrientation
