    ivy.el (ivy-done): Allow ivy-dispatching-done to exit with no cands
    
    Example of use:
    
    (defun ivy-recentf-with-last-input (_x)
      (ivy-read "Recentf: " recentf-list
                :action (lambda (f)
                          (with-ivy-window (find-file f)))
                :initial-input ivy-text
                :caller 'ivy-recentf))
    
    (ivy-set-actions t '(("r" ivy-recentf-with-last-input "recentf")))
    
    The input may match no candidates, but it's still good for
    `ivy-recentf-with-last-input', since it uses `ivy-text' instead of
    `ivy--current'.
