Client wrapper: issue with SOPC_ClientCommon_Connect if server is not reachable
The library crash during SOPC_ClientCommon_Connect
Analysis: In ToolkitEventCallback, we check with an assert if an event is not processed. In our case, one thread execute SOPC_ClientCommon_Connect which delete current client and another call ToolkitEventCallback. There is a race between these 2 threads which cause a crash on Windows
Fix: Change the assert by a log
