The aggregation count can't be applied to a CTE

[goldmedal]

Describe the bug The count(*) syntax can't be applied to a CTE. It's an issue responded to by the Discord community https://discord.com/channels/1227143286951514152/1285568489414856815/1285568647775129682 To Reproduce

Given the request body for preview API

{
  "manifest": {
    "catalog": "wrenai",
    "schema": "public",
    "models": [
      {
        "name": "customers",
        "refSql": "select * from main.customers",
        "columns": [
          {
            "name": "City",
            "type": "VARCHAR",
            "isCalculated": false,
            "notNull": false
          },
          {
            "name": "Id",
            "type": "VARCHAR",
            "isCalculated": false,
            "notNull": false
          },
          {
            "name": "State",
            "type": "VARCHAR",
            "isCalculated": false,
            "notNull": false
          }
        ],
        "primaryKey": "Id"
      }
    ]
  },
  "sql": "with t1 as (select * from customers) select count(*) from t1"
}

Then, got the error message

Caused by: java.lang.IllegalArgumentException: source node name not found: Table{t1, Optional.empty}

Expected behavior The SQL should work.
