"Connection: Close" disconnect bug

[SmorkalovG]

If there is a "Connection: Close" header, client does not receive body.
Here is the test case:

shared static this()
{
requestHTTP("http://127.0.0.1:80",
(scope req) {},
(scope res) {
assert(res.bodyReader.readAllUTF8() == "qwerty");
}
);
listenTCP(80, (TCPConnection c){
c.write("HTTP/1.1 200 OK\r\nConnection: Close\r\n\r\nqwerty");
}, "127.0.0.1");
}

Assertion fails, body is empty. Client closes connection right after parsing headers. It does not wait for body. Everything is ok if Content-Length is set. Bug can be reproduced using both 0.7.27 and 0.7.26. Just in case, section 5 in https://tools.ietf.org/html/rfc2616#section-4.4
