Description of problem:

The "Flatpak - Install application on host" REX job hangs for ~10 minutes until it finds out the underlying task is actually already done. Then it finishes with success.

How reproducible:

always

Is this issue a regression from an earlier version:

It is a regression since the job template uses `dbus-run-session` (for a good reason) instead of the original `dbus-launch`.

Steps to Reproduce:

1. Setup a Satellite and a RHEL9 host to install a Flatpak app.
2. Install a Flatpak app using the "Flatpak - Install application on host" job template.

Or just run robottelo test: pytest tests/foreman/cli/test_flatpak.py -k test_sync_consume_flatpak_repo_via_library[RedHat]

Actual behavior:
When you open the running job and click on the host it runs against, you see
