async-timeout==3.0.1
attrs==19.3.0
certifi==2019.11.28

To Reproduce

import asyncio
import stellar_sdk as stellar


async def orderbook():
    async with stellar.Server(
        horizon_url='https://horizon.stellar.org',
        client=stellar.client.aiohttp_client.AiohttpClient()
    ) as server:
        xlm = stellar.Asset.native()
        bat = stellar.Asset('BAT', 'GBDEVU63Y6NTHJQQZIKVTC23NWLQVP3WJ2RI2OTSJTNYOIGICST6DUXR')
        async for book in server.orderbook(bat, xlm).stream():
            print(book)


if __name__ == "__main__":
    asyncio.run(orderbook())

Expected behavior
Sequence of order book messages printed to console.

Probably the problem is somewhere here in aiohttp_client.py#L150. Orderbook events are sent by horizon without id and skipped by default.
