bug#74191: 31.0.50; file-directory-p broken when minibuffer-completing-file-name is non nil

[Thierry Volpiatto]

In Emacs-29:

(let ((minibuffer-completing-file-name t)) (file-directory-p "/ssh"))
=>nil

In Emacs-30+:

(let ((minibuffer-completing-file-name t)) (file-directory-p "/ssh"))
=> t

which is wrong obviously.
