tune_grid has conflicts with indicator names when columns are named the sense

library(tidymodels)
devtools::load_all()
library(mlbench)
data(Ionosphere)
Ionosphere <- Ionosphere %>% select(-V2) %>% mutate(cont = 1:nrow(.)) %>% as_tibble()

svm_mod <-
  rand_forest(mtry = tune(), trees = tune(), min_n = tune()) %>%
  set_mode("classification") %>%
  set_engine("ranger")

tflow <-
  Ionosphere %>%
  tidyflow(seed = 4943) %>%
  plug_split(initial_split) %>% 
  plug_formula(Class ~ .) %>%
  plug_resample(bootstraps, times = 5) %>%
  plug_model(svm_mod) %>% 
  plug_grid(grid_latin_hypercube, size = 5)

fit(tflow)

Once tune fixes this, this should be fixed on tidyflow as well. The problem was reported at tidymodels/tune#216
