Make icomplete-forward-completions O(1) when icomplete-scroll is t

In particular, this makes the recently added
icomplete-vertical-goto-last (bug#49005) be O(n) instead of O(n^2).
That used to be almost unbearably slow for large n.

* lisp/icomplete.el (icomplete-forward-completions):  don't call last
unless needed.
