HTTP header may be damaged - fix, unit test

"HTTP/1.1 100 CONTINUE\r\n" If the header from a server is splitted between two packets the first packet contains "HTTP/1.1 100" and the second one contains " CONTINUE\r\n", one space (0x20) is skipped. After processing the line looks in this way "HTTP/1.1 100CONTINUE". QHttpNetworkReplyPrivate::readStatus(QAbstractSocket *socket) is called twice, if a http header is splitted as above. The function always removes whitespace from the beginning of a packet, even if it is the second part of a http header QHttpNetworkReply returns QNetworkReply::RemoteHostClosedError due to damaged http header during processing.
