This patch modifies the test case 'test_video_stats_resistfingerprinting.html' to check media statistics report spoofed values when fingerprinting resistance is enabled. This test will play a video and test the media statistics when the video is finished. It will make sure all media statistics report correct spoofed values corresponding to the play time of the video.
