statistics: pass view to series

Browse source 
The series were passed a pointer to the QGraphicsScene to add
their item. In the future these items will be replaced by
QSGNodes. To add these, the series need a reference to the StatsView.
Therefore pass it in the constructor. Once everything is
replaces by QSGNodes, remove the QGraphicsScene member.
