Updating UserEventDispatcher to make some methods accessible.

> Removing helper methods around fillInLogContainerData so that its easier to
  create events with 3 and more srcTargets
> Removing setPredictedApps from userEventDispatcher as its specific to Launcher
  and does not apply to other activities. Instead moving it to AllAppsRecyclerView
