      Description

      Currently if users write such a SQL:

      `SELECT pyFunc5(f0, f1) FROM (SELECT e.f0, e.f1 FROM (SELECT pyFunc5(a) as e FROM MyTable) where e.f0 is NULL)`

      It will be optimized to:

      `FlinkLogicalCalc(select=[pyFunc5(pyFunc5(a)) AS f0])
      +- FlinkLogicalCalc(select=[a], where=[IS NULL(pyFunc5(a).f0)])
      +- FlinkLogicalLegacyTableSourceScan(table=[[default_catalog, default_database, MyTable, source: [TestTableSource(a, b, c, d)]]], fields=[a, b, c, d])`

      The optimized plan is not runnable, we need to fix this.
