    page: fix logic to propagate small-screen property from driver
    
    Since the driver is only set later to the page, and the initial value is
    FALSE, the actual value was never propagated down when the driver was
    set.
    This is relevant when the property is connected through a GBinding
    coming from the UI file, since the property binding is evaluated at
    init() time when property values are not yet available.
