Remove TiclSettingsProvider

It only had one method, UseGCMChannel(), plus corresponding observer
infrastructure. All UseGCMChannel() implementations always returned
true, so the whole thing can be removed.

Note: All the "PushClient" stuff from jingle/notifier should also be
removed eventually, but right now lots of tests still depend on it.
