0027322: geom/revolution_00/A1: Incorrect pcurve creation

Browse Source 
ProjLib_Cone.cxx - correction wrong calculation of projection line on cone
GeomInt_IntSS_1.cxx - modification of method BuildPCurves(...) - adjusting first or last knots of 2d Curve
ProjLib_ComputeApprox.cxx - modification of method Function_SetUVBounds(...) for case projecting line on cone.
Modification of tests - removing first TODO

Test case for issue #27322
