Fix T95202: Curve to mesh node inconsistent edge vertex order

Though the edge vertices aren't really meant to have an order,
it can make a difference in operations when there isn't any other
information to make decisions from, like etruding a circle of
loose edges (the situation in the report). This commit changes
the order of the vertices in the final cyclic edge to go in the
same direction as all of the other edges.
