Fix ReplaceWindowTests#testReplaceWindow_Dock_Relaunch() failure

Window was destroyed and added back when activity relaunched while
being moved from fullscreen stack to split-screen primary stack.
The activity window was recreated during the relaunch process
because RAC#ensureActivitiesVisible() executed recursively and
the inner calls override the setting to not preserve windows.

Avoid running RAC#ensureActivitiesVisible() recursively.
