Fix a bug where startCaptureOnCameraThread() is called while the camera is already successfully running. It may happen in the scenario when startCapture() is called, but startCaptureOnCameraThread() fails and posts a retry, then stopCapture() is called and removeCallbacksAndMessages() fails to remove the pending retry, and then startCapture() is called successfully.
