asyncio.streams.IncompleteReadError is removed from python3.8

https://github.com/aio-libs/aiomysql/blob/master/aiomysql/connection.py#L599 exception should be replaced

Upon running a stress test, I keep getting the error "AttributeError: module 'asyncio.streams' has no attribute 'IncompleteReadError'" and then my aiohttp server crashes. I installed aiomysql from master but did not fix.

Nevermind that. I see the branch referenced in the requirements file. It fixed my issue. She must be merged here.

Manky path:

def aiomysql_path():
  try:
    from aiomysql.connection import IncompleteReadError
    return
  except:
    pass

  try:
    from asyncio.streams import IncompleteReadError
    return
  except:
    pass

  import asyncio
  from pymysql import OperationalError

  async def _read_bytes(self, num_bytes):
    try:
      data = await self._reader.readexactly(num_bytes)
    except asyncio.exceptions.IncompleteReadError as e:
      msg = "Lost connection to MySQL server during query"
      raise OperationalError(2013, msg) from e
    except (IOError, OSError) as e:
      msg = "Lost connection to MySQL server during query (%s)" % (e,)
      raise OperationalError(2013, msg) from e
    return data

  from aiomysql.connection import Connection
  Connection._read_bytes = _read_bytes

Can you up lib version? Cause current version is too old and no fix at last release (0.0.20)
