Crash on canceling tranforming in emulator.

Nobody has claimed this yet.

When I try to cancel video transformin in the emulator, I receive such a crash. On my real device, I don't experience such issue.

Start with VideoFrameRenderFilter.release, GlVideoRenderer.release, VideoTrackTranscoder.stop, and TransformationJob.release, which appear in the emulator backtrace. Reproduce cancellation on the Android x86 emulator and trace the release sequence around glDeleteProgram. Done means canceling video transformation no longer crashes in the emulator while preserving normal cleanup on real devices.
