If you attempt to tree walk an AnalyticExpression in TableNamesFinder with an SQL that has a window function without a range and without an offset, such as `SELECT c, SUM(COUNT(*)) OVER (ORDER BY c ASC ROWS UNBOUNDED PRECEDING) FROM tbl GROUP BY c`, an NPE is thrown. This adds defensive checks around the range and offset expressions being null.
