    tests: Wait for signal unsubscriptions in gdbus-test-codegen
    
    When destroying `GDBusProxy`s in a custom `GMainContext`, the context
    must be iterated enough after finalisation of the proxies that any
    pending D-Bus traffic, and the signal subscription data, can be freed.
    
    See the documentation for `g_dbus_connection_signal_unsubscribe()`.

    Fixes: #2312
