bug#70773: 30.0.50; display-delayed-warnings does not respect display-buffer-alist

[Protesilaos Stavrou <info@protesilaos.com>]

Dear maintainers,

The display-delayed-warnings does not conform with display-buffer-no-window.

To test this, I create a new directory and write an init.el with the
following contents:

    (setq display-buffer-alist
          '(("\\`\\*\\(Warnings\\|Compile-Log\\|Org Links\\)\\*\\'"
             (display-buffer-no-window)
             (allow-no-window . t))))

Then I start Emacs with:

     emacs --init-directory=/path/to/testing/dir/

This produces the following:

    display-delayed-warnings: Wrong type argument: window-live-p, nil
    Error in delayed-warnings-hook (display-delayed-warnings): (wrong-type-argument window-live-p nil)

What I ultimately want is to not see those warnings at startup. I know I
can do it by setting the delayed-warnings-hook to nil, though there may
be a better option I have not discovered yet...

Thank you for your time,
Protesilaos (or simply "Prot")
