0028183: Modeling - BRepExtrema_DistShapeShape does not find all solutions

Browse Source 
Disable SetSingleSolutionFlag when calling algorithm of curve-curve Extrema.
Now DistShapeShape will find all solutions, even if they are located on the same pair of edges.
The fix brings the speed down for the cases of coinciding curves.
