Resource components were registered with the component updater but never
explicitly unregistered, causing it to keep downloading updates for
country and language models even after the ads service shut down or the
user opted out of notification ads. Components are now unregistered in
OnPrefChanged when the service becomes ineligible, and the language
component is additionally unregistered immediately when the user opts
out of notification ads while the service is still running.
