0028009: [Regression vs OCCT7.0.0] Cut produces not valid shape

Browse Source 
The algorithm in WorkWithBoundaries::BoundaryEstimation(...) did not take into account opposite directions of cylindrical axes (when the angle between them is obtuse). After the fix it does it.

Small correction of test cases for issue CR28009
