Right paren is removed when remove semi-colon in lisp-interaction-mode

[conao3]

In lisp-interaction-mode or something lisp like major-mode, when I remove semi-colon, puni also remove trailing right paren. Due to this behavior, paren balance become broken.

repro step

1. Save below file as ~/.debug.emacs.d/puni/init.el

   
   (prog1 "leaf"
   (custom-set-variables
   '(package-archives '(("melpa" . "https://melpa.org/packages/")
                       ("gnu"   . "https://elpa.gnu.org/packages/"))))
   (package-initialize)
   (use-package leaf :ensure t))

(leaf puni :ensure t :global-minor-mode electric-pair-mode puni-global-mode)

2. Load this init.el via `emacs --init-directory ~/.debug.emacs.d/puni`

3. Switch buffer to `*scratch*`

4. Type and occur issue. (`|` is cursor)

```elisp
;; type it
(a (b|))

;; type ;
(a (b;|))

;; backspace to remove ;
(a (b|

;; and you can see, right trailing paren is removed too.

It seems this issue comes from this code but I didn't figure out how to handle this.

Seeing the same behavior, it's very annoying when you accidentally type a semi-colon and it removes evrything following it on deletion.

I'm very sorry for the delay. This should be fixed now.
