Fix auto-layout of hierarchical elements

When applying auto-layout inside a hierarchical component, the layout
would also affect the position of the component's port at the outer
level.

Example: File > Open AF3 Example > Load ACC Example, open component
"AdaptiveCruiseControl" and perform automatic layout inside it. Open the
containing component "ACC System". The input ports of
"AdaptiveCruiseControl" will have shifted.
