Fix segmentation fault when creating sql tables failed

Browse source 
`GameServer()->OnShutdown(true);` (which would wait on running threads to exit)
wasn't called if an error occured in the server init. Therefore `CServer` was
freed before the init-thread finished executing, causing a use after free from
`CSqlConnector::ms_ppSqlReadServers` pointing to `CServer->m_apSqlReadServers`.
