Fix poly values mismerge

Fix poly values mismerge

I managed to completely mismerge correct values
for QuadraticCoefficientsOppositeColor table :-(

Now it correspond to tuning branch for real.

After 999 games at 1+0

Mod vs Orig +247 =512 -240 50.35%  503.0/999  +2 ELO

So almost no change, but the new values comes from the
same tuning session of the others, so has more sense to
use these ones.
