artist.el: Avoid error with keyboard command invocation

* lisp/textmodes/artist.el (artist-mouse-choose-operation):
Call x-popup-menu with t instead of last-nonmenu-event as the
value of the position argument; this allows invoking the
command from the keyboard without raising an error (bug#27819).
