bug#56371: Can't remove a package present in profil

[bbb ee]

Hi,

I have icedtea installed in my current profil, but `guix package remove` doesn't find it.

```
$ guix package -p ~/.guix-profile -I | grep icedtea
icedtea             3.19.0               jdk /gnu/store/5k7lsz61p8fq37c9x5p9xalryjxk31bs-icedtea-3.19.0-jdk
$ guix package -p ~/.guix-profile -r icedtea
guix package: error: package 'icedtea' not found in profile
```

It is a bug?
