    tests: Iterate mainloop during launch test
    
    When launching an application, we wait for the DBus response from
    systemd before executing the binary. Because of this the main loop needs
    to be iterated for spawning to completed and the file to be created.
    
    Without this the test will time out if GLib was able to connect to the
    session bus.
