#2846 has refactored the result set class. However the writeReplace method was not updated. This PR fixes it.
Impact: This will break the import export functionality in Pantheon and dataflow templates.

The error is as follows

Caused by: java.lang.IllegalArgumentException: Unable to encode element '[string_value: "Singers5"
, string_value: "1"
