bug#43222: 28.0.50; fido-mode selects wrong buffer to kill when no input

[Sean Whitton]

This is orthogonal to #43120 so far as I can tell.

1. emacs -q
2. M-x fido-mode RET
3. C-x C-f ~/src/emacs/lisp/icomplete.el RET
4. M-: (find-file (locate-library "icomplete.el.gz")) RET
5. C-x b icomplete.el RET
6. C-x k [wait for completions] RET|M-j

This should kill the buffer visiting icomplete.el (right?) but in fact
it kills the buffer visiting icomplete.el.gz.  The first completion
offered by fido-mode is different from the default value shown in the
minibuffer prompt.
