Revisit logging in `tune_bayes_workflow()`

[hfrick]

tune_bayes_workflow() contains two code comments about logging, one being an explicit TODO

tune/R/tune_bayes.R

Line 440 in 3544816

# Maybe remove .catch_and_log() here and do catching inside function

tune/R/tune_bayes.R

Lines 481 to 482 in 3544816

	# TODO move some messages here
	# check_and_log_flow(control, candidates)

check_and_log_flow() is currently unused. It's defined in R/logging.R but is only exercised by tests — this is its only (former) production call site. The function itself uses eval.parent(parse(text = "break")) to manipulate the caller's control flow, which is fragile.

tune/R/logging.R

Lines 449 to 476 in 3544816

	check_and_log_flow <- function(control, results) {
	if (!isTRUE(control$verbose_iter)) {
	return(invisible(NULL))
	}
	if (all(is.na(results$.mean))) {
	if (nrow(results) < 2) {
	update_printer(
	control,
	split_labels = NULL,
	task = "Halting search",
	type = "danger",
	catalog = FALSE
	)
	eval.parent(parse(text = "break"))
	} else {
	update_printer(
	control,
	split_labels = NULL,
	task = "Skipping to next iteration",
	type = "danger",
	catalog = FALSE
	)
	eval.parent(parse(text = "next"))
	}
	}
	invisible(NULL)
	}

If check_and_log_flow() is superseded, we should remove it and its tests, and clean up the comment.
