bug#53267: Profile changes after ‘guix upgrade --dry-run’

[Tirifto]

Hello! I recently had some issues with my setup, which had me rolling
my generations back and forth in attempt to fix them. My configuration
was at fault, but I did find an unrelated bug in Guix while at it:

When I run ‘guix package --rollback’, Guix switches to the previous
generation. But then, when I run ‘guix upgrade --dry-run’ to see what
would change again, my profile (~/.guix-profile/etc/profile) is actually
upgraded to the new generation. I should expect ‘--dry-run’ to leave my
profile untouched.

    repository URL: https://git.savannah.gnu.org/git/guix.git
    branch: master
    commit: 175915bb4417e198f6b500901dcef710a0011be9

I am using Guix as an additional package manager on top of
Trisquel GNU/Linux 9 ‘Etiona’.

Best of wishes
