Use different method of finding a point in the face if the start and projected points are close to each other.

2. method Standard_Real MinStep3D(const TopoDS_Edge& theE1,
                        const TopoDS_Face& theF1,
                        const BOPTools_ListOfCoupleOfShape& theLCS,
                        const gp_Pnt& aP)
The min 3D step has been increased for the spherical faces.
