Open chrome://hitograms after a video is ended in ChromeVidResChangeHWDecode test

ChromeVidResChnageHWDecode opens chrome://histograms to check
Media.GpuVideoDecoderInitializeStatus value while a test video is played.
Because of that, the video played tab becomes background.
Since Chrome pauses a video in background tab, the test is failed because it
detects a test video is unexpectedly stopped.
To fix this failure, the test opens chrome://histograms after a test video is ended.
