webrtc/video-replace-track.html

Has been flaky failing on iOS since the test was introduced on that platform. It fails on both debug and release. 

The test has also been flaky timeout on macOS but I am making a separate bug for that as there are other tests timing out with it on that platform.

This is reproducible  by running the rest in iterations with this command ‘run-webkit-tests --root BUILD webrtc/video-replace-track.html --ios-simulator --iterations 2000 -f --force’
