    tests: Ensure GTK resources are registered for icon test
    
    The GTK icon resources are needed for the icon test, and they’re
    compiled into libgtk. Normally they’re registered when `gtk_init()` is
    called, but we can’t call that in the tests as they’re often run
    headless.
    
    Call `gtk_init_check()` instead. It will fail to completely set up GTK,
    but will not abort the program, and will successfully register the
    resources first.
