Summary

Fixes deprecated JSON serialization version 0 for LowCardinality(Nullable(String)) and similar types.

LowCardinality is a type that has a prefix in the Native format, so this fix applies to similar columns that implement a prefix.

This is not an issue for serialization version 3 from #1590, only this older version.

Checklist

  • Unit and integration tests covering the common scenarios were added
