Note: As many other tests do something similar to this, let me work on this in a
following CL.

This name is confusing. Can you change it to ArcAvailableDisallowed?

Done.

Is this test case no longer needed? If so, also update
chromeos_info_private/extended/background.js.

[hidehiko, 2017/01/24 18:05:56]

Good catch. Done.
