sql: debug zip omits user-created tables in `crdb_internal.create_statements.txt`

I've seen a debug zip from a v22.2.6 cluster where the `crdb_internal.create_statements.txt` file does not contain user-created tables, and the `crdb_internal.create_statements.txt.err` file contains an error:

```

```

I have not yet tried to reproduce this, but I'd start by adding a type, dropping the type, and then running the query that collects the contents of the `crdb_internal.create_statements.txt` file in the debug zip.
