Don't set timeout for receiving a message before sending the first one.

/*
 * Tell the TCP- or TLSClient to notify if

 * - a timeout has occurred while waiting for the respective response message
 */

// Set TLS security flag for communication session
boolean secureConn = (((Byte) getSecurity()).compareTo((Byte) GlobalValues.V2G_SECURITY_WITH_TLS.getByteValue()) == 0) ? true : false;
getV2gCommunicationSessionEVCC().setTlsConnection(secureConn);

sendSupportedAppProtocolReq();

The timeout for receiving a message in TCPClient/TCPClient can expire before SupportedAppProtocolReq is sent if the creation of an evController takes too long (in new V2GCommunicationSessionEVCC).
