`print.canned_pred` checks contents of non-existent `pre` (partial-matched to unintended element)

Line 115 in 7f08d40

if ("actions" %in% names(x$pre) && "recipe" %in% names(x$pre$actions)) {

print.canned_epipred <- function(x, name, ...) {
[...]
  if ("actions" %in% names(x$pre) && "recipe" %in% names(x$pre$actions)) {

Presumably, x$pre is supposed to be the preprocessor, but it actually partial-matches to x$predictions.

musing: if not for this coincidence, warnPartialMatchDollar wouldn't have even caught this and we'd just be testing vs. NULL. This is also an issue for epi_archives. (And also epi_dfs though for attrs not list elts.) Is there any sort of list subclass that makes $/attr do exact matches and produce an error rather than NULL when the requested key has no match?

Hey could you tag these new issues with priority + size estimates and bucket them into backlog/icebox please? Should be easiest when freshly filed and the context is clear.

I'm just guessing here.
