We should probably replace this usage of
cr-policy-pref-indicator+paper-togggle-button with a settings-toggle-button, see
https://cs.chromium.org/chromium/src/chrome/browser/resources/settings/contro....
Either way, I'll leave that for a future cleanup, since my priority is to fix
the tests and unblock Vulcanization.

We could also use a browser proxy from date_time_page.js instead of directly
calling chrome.send, but I'll leave that for a future cleanup as well.
