[erlang-bugs] Fix {stream, {self, once}} in httpc

[Masatake Daimon]

Hello,

Previously the only difference between {stream, self} and {stream,
{self, once}} was an extra Pid in the stream_start message due to a
bug in httpc_handler. It was immediately sending a bunch of messages
till the end instead of waiting for httpc:stream_next/1 being called.
