constraintlayout: Make sure guides get their constraints

Browse Source 
When using GtkBuilder to create constraints and guides,
the layout manager is already rooted when the guides get
created, and we were forgetting to create the guides
constraints in this case. Fix it by adding a call to
gtk_constraint_guide_update().

This was showing up in the new builder-based constraints
demo as the guide not having the expected effect.
