[TEST] Remove redundant codes in SVD++
## What changes were proposed in this pull request?
```
val newVertices = g.vertices.mapValues(v => (v._1.toArray, v._2.toArray,
v._3, v._4))
(Graph(newVertices, g.edges), u)
```
`g` is of type `Graph[(Array[Double], Array[Double], Double, Double),
Double]`,
and the return value seems just equal to `(g, u)`
## How was this patch tested?
no test now
I will create the JIRA if all tests pass
