This is a reland of 9b4fd545

This fixes the original CL by moving where setCaptureActive() is called
to allow the first replay source file to be written.

Original change's description:
> Capture/Replay: Reset GL Fence Sync objects
>
> Asphalt 9 uses GL Fence Sync objects during rendering, which results in
> Fence Sync objects being created during setup and deleted while
> replaying frames. When the replay is restarted, the Fence Sync objects
> that were created during setup and deleted during the replay need to be
> recreated during the reset phase.
