Silent `@EACH()` failure when second argument matches column name in node

[tjirab]

When the second argument in an @EACH() function call matches a column in the node, it seems to be ignored.

SQLMesh definition

SELECT
  organization_id,
  @EACH(
    @product_families_simple,
    product -> (
      MIN(CASE WHEN product = @product AND rownum = 4 THEN reference_date END)
    ) AS @{product}_low_engagement_date
  ),

Compiled SQL

SELECT
  `_pql_qualifying_days`.`organization_id` AS `organization_id`,
  MIN(
    CASE
      WHEN `_pql_qualifying_days`.`rownum` = 4
      THEN `_pql_qualifying_days`.`reference_date`
    END
  ) AS `feeds_low_engagement_date`,

When adding a prefix, it compiles correctly.
