Add context object to screenScaleChanged connection
Currently internal window test fails because several internal clients
outlive tests where each one of them was created. Given that the scene
doesn't specify the context object when it creates screenScaleChanged
connection, we may call windowGeometryShapeChanged on a deleted scene
object.
