## What changes were proposed in this pull request?
Fixed wrong documentation for Mean Absolute Error.
Even though the code is correct for the MAE:
```scala
@Since("1.2.0")
def meanAbsoluteError: Double = {
summary.normL1(1) / summary.count
}
```
In the documentation the division by N is missing.

All of spark tests were run.
