    tests: Avoid race condition in threaded tests
    
    Calling soup_server_run in a new thread, and calling
    soup_server_get_port() on the same SoupServer instance
    right after creating the thread.
    With recent libsoup, this sometimes causes a crash when the 2 threads
    try to call soup_server_ensure_listening() at the same time.
    Moving the call to soup_server_get_port() before the thread creation
    avoids this race condition.
