Fixes broken BSP lookup in QGraphicsSceneBspTreeIndex.
The chip demo was unbelievable slow, so I investigated and found out
the bsp always returned almost all items in the tree (40 000 in this
particular case). It did so because the tree was initialized with
an empty sceneRect. The sceneRect was empty due to a lacking signal-slot
connection, resulting in QGraphicsSceneBspTreeIndex::updateSceneRect
never being invoked.
Auto-test included.
