Pytest_asyncio event loop replacement deprecated

[mhamid3d]

In the conftest.py the event loop is being replaced with a new one. This is no longer supported with pytest_asyncio and results in this warning:

Replacing the event_loop fixture with a custom implementation is deprecated
  and will lead to errors in the future.
  If you want to request an asyncio event loop with a scope other than function
  scope, use the "scope" argument to the asyncio mark when marking the tests.
  If you want to return different types of event loops, use the event_loop_policy
  fixture.
