Subject: Replace remaining uses of event_loop fixture

The test suite started failing with pytest-asyncio >= 1.0.0, as that
version removed the deprecated `event_loop` fixture.  Finish the work of
replacing it that was started in
https://github.com/aresponses/aresponses/pull/76.

 If you're trying to use the `aiohttp_client` test fixture then you'll need to mock out the aiohttp `loop` fixture
 instead:
 ```python
-@pytest.fixture
-def loop(event_loop):
-    """replace aiohttp loop fixture with pytest-asyncio fixture"""
-    return event_loop
+import pytest_asyncio
+
+@pytest_asyncio.fixture
+async def loop():
