Fix when a method is passed as an endpoint and init CBV #126

[taoufik07]

ref #126 #127

[taoufik07]

@kennethreitz I see that you've removed websockets, this PR fixes the Route.is_function + the websocket problem (the issues that I've reported before)

[taoufik07]

@kennethreitz and I was about to add the last peace of the puzzle but you've closed the PR :/

A way of consuming websockets and handling Abnormal close
UPDATE

async def ws2(ws, greeting):
	await ws.accept()
	try:
		while True:
			name = await ws.text()
			print(name)
			await ws.send_text(f"{greeting} {name} via ws!")
		await ws.close()
	except WebSocketDisconnect as e:
		print("Closed by the client")
	finally:
		print("post stuff")
