0028491: Incomplete section curve

Browse Source 
The main idea of the fix is to forbid check if intersection curve lies in the some face (with input tolerance) if we have 2D-intersection curve on this face (we consider that necessary tolerance has been computed in intersection algorithm honestly). If we do not have 2D-curve on this face then we need check as before.

New algorithm is implemented in IntTools_Context::IsValidBlockForFaces(...) method.
