Commit fixes the bug from issue #2048

The bug occurs when using the autoascent feature for
negative inclination orbits. Namely, the circularization burn was
explicitly trying to achieve the _abs(inclination)_ instead of the target.

The bug was fixed by removing the `Math.Abs()` from the
OrbitalManeuverCalculator.DeltaVToChangeInclination input.
