[Contextual Edu] Update Edu stats when going to overview and all apps from home

Update education stats when
- go overview and all apps by swiping up at homepage (AbstractStateChangeTouchController)
- go home from all apps by swiping down the all apps panel (AbstractStateChangeTouchController)
- go home from all apps or overview by swiping up from the bottom nav bar (NavBarToHomeTouchController)
- in 3 button navgiation mode (TaskbarNavButtonController)

NavBarToHomeTouchController does not inherit from AbstractStateChangeTouchController so logic are added separately.
