  Do not update hasOutlineAutoAncestor when moving out a spanner's renderer

Reviewed by Alan Baradlay.

When we move out a spanner's renderer, we might set the renderer as having
a hasOutlineAutoAncestor value of true and leave the spanner placeholder
with a hasOutlineAutoAncestor value of false. This is because when we move
out the spanner's renderer we set hasOutlineAutoAncestor based on its new
parent. However we want to maintain a value consistent with spanner's placholder.

* Source/WebCore/rendering/RenderObject.cpp:
(WebCore::RenderObject::propagateRepaintToParentWithOutlineAutoIfNeeded const):
We want to check if the originalRenderer needs a repaint, not the placeholder.

* Source/WebCore/rendering/updating/RenderTreeBuilder.cpp:
(WebCore::RenderTreeBuilder::attachToRenderElementInternal):
