rename_ard_columns(unlist) messaging

Code
  head(rename_ard_columns(dplyr::mutate(ard_categorical(ADSL, by = ARM,
    variables = AGEGR1), stat = ifelse(dplyr::row_number() == 1L, list(median),
  stat)), unlist = stat), 1L)
Message
  Unable to unlist column "stat".
  i This often occurs when a list column contains elements that cannot coerced to a common type.
Output

Code
  rename_ard_columns(dplyr::mutate(ard_categorical(ADSL, by = ARM, variables = AGEGR1),
  stat = ifelse(dplyr::row_number() == 1L, list(NULL), stat)), unlist = stat)
Condition
  Error in `rename_ard_columns()`:
  ! Cannot unlist column "stat". The unlisted result is not the same length as the original.
  i This often occurs when the column contains `NULL` values.
  * Run `cards::replace_null_statistic()` to replace `NULL` values with NA.
