SGD DistanceConstraintAggregation order of contraints bug

If the order of the constraints is switched below, the code errors out:

DistanceConstraintAggregation(
    [  # TODO: BUG; must maintain the order of constraints
        SpacingConstraint(min_spacing=min_spacing),
        constraint_comp,
    ],
    n_wt=n_wt * 2,
    min_spacing_m=min_spacing,
    windTurbines=wind_turbines,
)

I found out about this in reading sgd_slsqp_comparison.ipynb:

... The constraints for the SGD driver are defined with the DistanceConstraintAggregation class.
Note: as the class is specified, the order of the SpacingConstraint and XYBoundaryConstraint **must** be kept as shown in this example.

Seems quite unreasonable to leave this out for a user to find out by themselves. An easy workaround could be ordering the list in the class before anything else. Or fixing the issue... Could take a shot at this once we have a direction : )
