fix: updates tests based on revised hacker_news tables (#1591)

This fixes four broken tests that failed due to an unexpected change in the Google Public Dataset: Hacker News.

The `comments` table was deleted and only the `full` table remained.

This edit updates the name of the table in four tests and updates the names of columns in the table as well as updates the expected results for one of the tests.

Fixes #1590 🦕
