melodie-swtich: Column order for `tune_results$.predictions` changed

[hfrick]

With https://github.com/tidymodels/tune/tree/melodie-switch:

The .predictions data frame of a tune_results object has a different column order now. It affects censored regression.

• tests/testthat/test-survival-tune-grid.R
• tests/testthat/test-survival-tune-bayes.R (first 3 tests)
• tests/testthat/test-survival-tune-sa.R

> expect_equal(
+     names(bayes_static_res$.predictions[[1]]),
+     c(".pred_time", ".row", "tree_depth", "event_time", ".config")
+   )
Error:
! names(bayes_static_res$.predictions[[1]]) (`actual`) not equal to c(".pred_time", ".row", "tree_depth", "event_time", ".config") (`expected`).

`actual`:   ".pred_time" ".row" "event_time" "tree_depth" ".config"
`expected`: ".pred_time" ".row" "tree_depth" "event_time" ".config"

#265 switches to using expect_named() for the column names and adds ignore.order = TRUE, so those failures go away (but the cause isn't addressed yet!).

We can use this issue here to track our intention of removing that argument again and addressing any remaining order issues.
