Fixed dockContainer() function of AutoHideDockContainer.cpp

Returning the dock container of the internal dock area is wrong, if the dock widget is removed from
the AutoHideDockContainer, then the DockArea container function already returns the new dock container
of the DockArea and not the dock container of the AutoHideDockContainer.cpp
