Remove OverviewToAllAppsController for Go

Go's recents does not support an overview to all apps transition (as
there will be no hotseat and swiping will be used to navigate the view
itself). As a result, we never need the controller, so we don't take in
the class as a source and do not add it as a touch controller.
