Do not send the client URL to network process when unregistering a service worker registration

Do not send the client URL to network process.
This is unnecessary and somehow unsafe.

I think this would read better like this:

    auto iterator = m_clientOrigins.find(clientIdentifier);
    if (iterator == m_clientOrigins.end())
        return { };
    auto clientData = server().serviceWorkerClientWithOriginByID(iterator->value, clientIdentifier);
    if (!clientData)
        return { };
