I've rebase onto master, and fixed the test. Lets wait for the CI's opinion
of the fix.
The problem was the following, introduced in
https://github.com/apache/spark/pull/21221:
``
scala> None == null
res0: Boolean = false
```
We need to override the isEmpty of the serializer to verify if the
`Option[_]` is Empty or not.
