bug#50732: 28.0.50; project-find-dir: blank line in fido-vertical-mode

[Manuel Uberti]

This is a quick recipe:

- emacs -Q
- M-x fido-vertical-mode RET
- C-x p d
- choose a project (I picked my .emacs.d directory)
- there is a blank line between the prompt and the list of candidates
- see attached screenshot for details
