{{compact_value}} in 3.0 is (correctly) being turned into {{Kind.REGULAR}}, but
the original kind is important when decoding the name for super columns.
Without the patch, the {{compact_value}} column is being treated like a regular
defined counter super column from {{column_metadata}}. After the patch, it's
properly special cased and is correctly decoded using {{UTF8Type}}.
