bgo #721407 - Fix scrolled window to work with template subclasses.

Browse Source 
Ensure the hscrollbar & vscrollbar at gtk_scrolled_window_add() time,
this allows one to subclass GtkScrolledWindow with templates and add
children, as this will happen at instance initialization time before
the construct adjustment properties take effect.
