    tests: Fix loading project with moved asset and deleted proxies
    
    Now that loading projects is done in two passes, there is enough time
    for proxies to be created before the project is loaded, the race always
    existed but recent changes in GES reveals it.
    
    Make sure that all proxies are created to stop the mainloop.
