DBus interface is always present, and inspecting it auto-starts the app

[gergelypolonkai]

I was inspecting the DBus interface of another app, and i misclicked in d-feet. When the interface details got expanded, the Workbench app (installed from Flathub) immediately launched. I’m not exactly sure this is a bug or not, but i know i couldn’t reproduce it with any other apps/interfaces.

To reproduce

1. make sure the app is closed
2. open d-feet (or any other DBus introspection tool)
3. inspect the re.sonny.Workbench bus

or, if you don’t have a graphical introspection tool,

dbus-send --session \
          --dest=re.sonny.Workbench \
          --type=method_call \
          --print-reply \
          / org.freedesktop.DBus.ObjectManager.GetManagedObject

(note that this will return an error, but the app opens nevertheless).
