Fallback to HTTP1 when HTTP2 is not negotiated

Browse source 
If the server doesn't support ALPN or NPN, negotiated_protocol will be
None. That meant that transport_type wouldn't be set, in which case nio
will raise a NotImplementedError. Instead, set transport_type to HTTP if
nothing is negotiated.
