Checking for invalid property of QRemoteObjectDynamicReplica crashes in QMetaObject::indexOfProperty

1. Edit the QT remoteobjects example, directconnectdynamicclientDynamicClient::recSwitchState_slot; add an extra character to the requested property name to make it invalid (as below)

2. void DynamicClient::recSwitchState_slot(bool value)
   {
   clientSwitchState = reptr->property("currStateX").toBool(); // use replica property to get "currState" from source qDebug() << "Received source state " << value << clientSwitchState; Q_EMIT echoSwitchState(clientSwitchState); // Emit signal to echo received state back to server
   } 

3. Run directconnectserver.
4. Run directconnectdynamicclient in debugger.
5. Note crash occurs in QMetaObject::indexOfProperty

Expected behaviour - indexOfProperty returns -1
