Why do we now need to register these two prefs? (I'm mostly just curious)

[ftang, 2016/05/03 23:55:42]

without doing so, the unit test will break in some platform while it try to read
them.

Acknowledged.

Should this use preferred_languages_prefs? (maybe doesn't work on non-cros?)

[ftang, 2016/05/03 23:55:42]

ChromeOS use one of them and non ChromeOS use another one. I just register both
in all cases to make the unit test simpler and won't break on any platform.
