renew cached objects for testing

[topepo]

Scales 1.3.0 made a change in the object class of its transformers. Their new class ("transformers") is not compatible with the old class (see below). We need to recreate these with the new version of scales.

library(tidymodels)
library(testthat)

#> The following object is masked from 'package:tidyr':
#>

#> The following object is masked from 'package:rsample':

#> The following object is masked from 'package:purrr':
#> 
#>     is_null
#> The following object is masked from 'package:dplyr':
#> 
#>     matches
