Tests: fixed stream_proxy_ssl_conf_command.t.
The stream_proxy_ssl_conf_command.t test used stream return module
to return the response. Since this ignores actual request, but the
perl test code used http_get(). This might result in the request being
sent after the response is returned and the connection closed by the server,
resulting in RST being generated and no response seen by the client at all.
Fix is to use "stream(...)->read()" instead of http_get(), so
no request is sent at all, eliminating possibility of RST being
generated.
