nit: if you expect this to always be non-empty, wrap it in assert()

  chrome.send('performResetProfileSettings',
      [$('send-settings').checked,
       assert(ResetProfileSettingsOverlay.resetRequestOrigin_)]);

An empty string is ok to be passed here. It can happen, for example, if user
navigates to chrome://settings/resetProfileSettings from the omnibox.
