S2CellUnionTests Line 258-260 should be removed.

[GoogleCodeExporter]

Line 258-260 as below should be removed:

            if (!u.contains(xId)) {
              u.getIntersection(xCells, yId);
            }

It is extraneous and guarantees the subsequent assertTrue(u.contains(xId)); on 
line 261 will always work even though this is the line that is being ultimately 
tested.
