    Fix race in socketclient-slow test
    
    This test ensures that g_socket_client_connect_to_host_async() fails if
    it is cancelled, but it's not cancelled until after 1 millisecond. Our
    CI testers are hitting that race window, and Milan is able to reproduce
    the crash locally as well. Switching it from 1ms to 0ms is enough to
    avoid the crash, but let's be extra-cautious and use G_PRIORITY_HIGH
    as well, for good measure.
    
    This was discovered in #2221, but sadly it's not enough to resolve that
    issue.
