[SPARK-10459][SQL] Do not need to have ConvertToSafe for PythonUDF
JIRA: https://issues.apache.org/jira/browse/SPARK-10459
As mentioned in the JIRA, `PythonUDF` actually could process `UnsafeRow`.
Specially, the rows in `childResults` in `BatchPythonEvaluation` will be
projected to a `MutableRow`. So I think we can enable `canProcessUnsafeRows`
for `BatchPythonEvaluation` and get rid of redundant `ConvertToSafe`.
