Should we wait to remove these tests for when we remove tray_cast, etc?

[jdufault, 2016/10/27 18:38:08]

tray_cast isn't going away, but the code this tests is.

https://codereview.chromium.org/2424183002/ removes it.

Can you add imcheng@ as a reviewer to the change if you are adding any new
behavior that uses the Media Router?
