Coroutine sink exceptions are not caught

It appears that if you use a coroutine as a sink and it has an unhandled exception, even with catch=True specified in add(), the exception is not caught, and you will get a Task exception was never retrieved error on stderr from asyncio: https://docs.python.org/3/library/asyncio-dev.html#detect-never-retrieved-exceptions

import asyncio
from loguru import logger

async def sink(msg):
  raise Exception("oh no")

async def main():
  logger.add(sink, catch=True)
  logger.info("hello world")

asyncio.run(main())

2020-03-23 12:31:58.236 | INFO | main:main:3 - hello world Task exception was never retrieved future: <Task finished name=‘Task-2’ coro=<sink() done, defined at <stdin>:1> exception=Exception(‘oh no’)> Traceback (most recent call last): File “<stdin>”, line 2, in sink Exception: oh no

Fixed in next version. 😃

Great, so we agree on how this should behave. 👍

I’m a little worried about the callback overhead but I don’t see any other simple solution.
