0033615: Modeling Algorithms - Partition algorithm creates unexpected vertices

This problem occurs because of obtaining 2 ALines which share same vertex on the seam edge.
There should be 2 different vertices with same(or almost the same) 3d parameters, but
with different UV parameters because of periodic surface.
Current fix allows to avoid the same vertices on seam edge and also checks the next vertex.
