Global accessibility action to open recent apps shows the old dialog style.

1. The global action to open recent apps shows the old dialog style rent apps
   panel. Apparently the key code to open recent apps is not opening the new
   UI so the AccessibilityManagerService is calling directly the method on
   the IStatusBarSerivce to do so.
