wireproto: explicit API to create outgoing streams

It is better to create outgoing streams through the reactor so the
reactor knows about what streams are active and can track them
accordingly.

Test output changes slightly because frames from subsequent responses
no longer have the "stream begin" stream flag set because the stream
is now used across all responses.
