[BUG] pkg.group_installed says group is partially installed and will be updated when test=true

Description
Running salt state.sls with test=true indicates there is a change to be applied when a package is included in pkg.group_installed.

Setup
Example sls:

pkgs_group_desktop_environment:
    pkg.group_installed:
        - name: xfce-desktop
        - skip:
            - xfce4-power-manager
        - include:
            -  pinentry-gtk #conditional package

• on-prem machine
• onedir packaging

Steps to Reproduce the behavior

salt-call --state-verbose=false --state-output=changes state.sls yann.test test=true
local:
----------
          ID: pkgs_group_desktop_environment
    Function: pkg.group_installed
        Name: Xfce
      Result: None
     Comment: Group 'Xfce' is partially installed and will be updated
     Started: 17:02:36.844530

And nothing applied when running without test=true

salt-call --state-verbose=false --state-output=changes state.sls yann.test saltenv=base pillarenv=base
local:

Summary for local

Start by locating the implementation and tests for the pkg.group_installed state, then reproduce the behavior with test=true using the provided SLS example. Compare the test-mode result with the normal run and add coverage showing that an unchanged group does not report a pending update; done means the reproduced state reports no change.
