We shouldn't add this here until we use it.

[Kyle Horimoto, 2017/04/19 22:31:04]

Without this change, the settings page has a JavaScript error below on the line:

newNetworkStateLists[type].push(networkState);

We need to include this edit with this CL to prevent breakage.

[stevenjb, 2017/04/19 22:37:34]

What's the error? We should probably fix that instead (e.g. test
newNetworkStateLists.hasOwnProperty(type) first).

[Kyle Horimoto, 2017/04/19 23:08:59]

Done.
