    GH-33779: [R] Nightly builds (R 3.5 and 3.6) failing due to field refs test (#33780)
    
    This PR fixes a test which is failing on R versions < 4.0 due to the use of the function `data.frame()` which had a change in default parameter value for `stringsAsFactors` (from `TRUE` to `FALSE`) in 4.0, and so is behaving differently in these versions.
    
    I've just swapped out the use of `data.frame()` for `tibble::tibble()` , which we use more prevalently in our tests, and has no such issues on earlier R version.
    
    * Closes: #33779
