Fix wrong function call on asyncio

[thiagoalessio]

Python 3.6.15

>>> import asyncio

>>> async def hello():
...   print("Hello")

>>> asyncio.run(hello())
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: module 'asyncio' has no attribute 'run'

>>> asyncio.get_event_loop().run_until_complete(hello())
Hello
