Do not generate fake values when adding an auto-inc column to a versioned table. This is not a auto-inc issue, but a more general case of adding a not nullalble unique column to a table with history. We don't support it yet, not even with a special auto-inc hack. As a workaround, one can use a nullable unique column, that works.
