bug#50978: "guix home describe" backtraces if "guix home" hasn't been used

[Maxime Devos]

Hi,

When running "guix home describe" before "guix home import"
and before "guix build":

$ guix home  describe
Backtrace:
           7 (primitive-load "/home/[...]/.config/guix/current/b…")
In guix/ui.scm:
   2185:7  6 (run-guix . _)
  2148:10  5 (run-guix-command _ . _)
In ice-9/boot-9.scm:
  1752:10  4 (with-exception-handler _ _ #:unwind? _ # _)
In guix/status.scm:
    820:3  3 (_)
    800:4  2 (call-with-status-report _ _)
In guix/scripts/home.scm:
    263:8  1 (_)
In ice-9/boot-9.scm:
  1685:16  0 (raise-exception _ #:continuable? _)

ice-9/boot-9.scm:1685:16: In procedure raise-exception:
no home environment generation, nothing to describe~%

I don't think a backtrace is needed here.

Greetings,
Maxime
