    tests: Use G_TEST_OPTION_ISOLATE_DIRS in gdbus-peer-object-manager
    
    This might fix a recent test failure:
    https://gitlab.gnome.org/GNOME/glib/-/jobs/1929015. Unfortunately
    there’s not much debug information in the logs to go on, and I can’t
    reproduce it locally. All I have is:
    ```
