Renaming with aliases generates invalid SQL

[rm-hull]

(testing "simple renaming"
  (are [x y] (= (-> x (compile nil) interpolate-sql) y)
       (-> (table :users)
           (project [:users.id])
           (rename {:users.id :idx}))
       "SELECT users.id FROM users AS users(idx)"))

(testing "renaming with a table alias"
  (are [x y] (= (-> x (compile nil) interpolate-sql) y)
       (-> (table {:users :people})
           (project [:people.id])
           (rename {:people.id :idx}))
       "SELECT people.id FROM users people AS people(idx)"))

Second test fails as generated SQL is: SELECT people.id FROM users people AS users people()
