0028221: General Fuse operation error

Browse Source 
The method BOPTools_AlgoTools2D::AttachExistingPCurve has been corrected so that
to call BRepLib::SameParameter not on the target edge with the whole set of pcurves,
but rather on a temporary edge with 3D curve and copied pcurve only.
After that the updated pcurve is transferred to the target edge.

Small correction of test case for issue CR28221
