Fix the flushing of messages when switching to Websocket

We now flush messages that are specific to cowboy_http only.

Stream handlers should also flush their own specific messages
if necessary, although timeouts will be flushed regardless
of where they originate from.

Also renames the http_SUITE to old_http_SUITE to distinguish
new tests from old tests. Most old tests need to be removed
or converted eventually as they're legacy tests from Cowboy 1.0.
