Bug 1022992 - Always display Find My Device's enabled status in the Settings menu.

Only tangentially. This is something Kate mentioned in passing in the initial report (comment 0 in the bug):

> When you click on FMD, if it is enabled as it was in my case, you will see that it is enabled with the blue toggle bar. However, it will flash the sign in screen for about a minute before showing the toggle bar."

I completely agree with you that the scope of the bug here is that the Enabled/Disabled status is not shown in the root panel, but I thought I'd also include this fix in a separate commit in the same PR, as it is a one-line change anyway. Should I file a separate bug instead?
