check_name() is used

Code
  prep(rec, training = dat)
Condition
  Error in `step_bs()`:
  Caused by error in `bake()`:
  ! Name collision occurred. The following variable names already exist:
  * `mpg_bs_1`

bake method errors when needed non-standard role columns are missing

Code
  bake(with_bs, new_data = biomass_tr[, c(-4)])
Condition
  Error in `step_bs()`:
  ! The following required column is missing from `new_data`: hydrogen.
