check_col works in the bake stage

Code
  rp1 %>% check_cols(all_predictors()) %>% prep() %>% bake(mtcars[-1])
Condition
  Error in `bake()`:
  x The following required columns are missing from `new_data`: `mpg`.
  i These columns have one of the following roles, which are required at `bake()` time: `predictor`.

Code
  rp2 %>% check_cols(cyl, mpg, drat) %>% prep() %>% bake(mtcars[, c(2, 5)])
Condition
  Error in `bake()`:
  x The following required columns are missing from `new_data`: `mpg`.
  i These columns have one of the following roles, which are required at `bake()` time: `predictor`.

non-standard roles during bake/predict

Code
  predict(role_wts_fit, head(Chicago) %>% select(-date))
Condition
  Error in `hardhat::forge()`:
  ! The required column "date" is missing.

Code
  predict(rm_fit, Chicago %>% select(-date))
Condition
  Error in `hardhat::forge()`:
  ! The required column "date" is missing.

Code
  predict(rm_fit, Chicago %>% select(-date))
Condition
  Error in `hardhat::forge()`:
  ! The required column "date" is missing.
