Review comment:
I think it's because `as.data.frame()` returns a `data.frame` object
whereas `dplyr::collect()` returns a `tibble` object, so while the objects
returned contain the same values, they are of different classes (which is
something that `expect_identical` checks for).
Updating the expected return value to be created via `data.frame()` instead
of `tibble::tibble()` would fix this.
