bug#57585: guix gc removed home config

[Julien Lepiller <julien@lepiller.eu>]

Actually I figured this out:

Generation 16 used an older guix version where guix home added a . at
the end of file names, so my config looked like this:

(simple-service 'xfce4-terminal home-files-service-type               
  `(("config/xfce4/terminal/terminalrc"
    ,(local-file
      "files/xfce4-terminal/terminalrc"))))

Then, I updated Guix without changing my home configuration, so on
generation 17, guix home created $HOME/config instead of $HOME/.config.
So $HOME/.config/xfce4/terminal/terminalrc (and all other config files)
kept pointing to generation 16's files. After removing the generation
and "guix gc", these files no longer exist, and I'm in trouble :)

So, guix home and guix gc are working as intended, but the change to no
longer adding a "." at the beginning of file names (which makes total
sense) tripped me up.
