Incorrect calculation of forces/moments coefficients with older versions of SU2

Hi SU2 Team

I recently took part in validation study for a trapezoidal wing geometry
using SU2 version 2.0.

The forces/moments coefficients predicted by SU2 2.0 were erroneous.
In fact upto SU2 version 2.0.4, the forces/moments calculations are incorrect.
SU2 2.0.5 is giving correct values of forces/moments coefficients.

I am attaching CL and CD comparison for SU2 versions 2.0, 2.0.4 and 2.0.5
obtained for same mesh and configuration file.

SU2 2.0.5 is giving correct results (matched with experimental values)

Please look into it.

Thanks
