QGraphicsItem::childrenBoundingRect behavior breaks QGraphicsEffect::sourceBoundingRect().

Context:
QGraphicsEffect::sourceBoundingRect() returns:
item->boundingRect() | item->childrenBoundingRect();

Problem was that item->childrenBoundingRect() adjusted the children's
bounding rect with the children's ancestor effects (child -> root item),
which means the source bounding rect was bigger than needed. We should
only account for effects downwards in the hierarchy.

   root (has effect)
    |
   item (has effect)
    |
  child
    |
grandChild

Auto test included.
