Fix CI issue seen in the PR #48

(I preferred opened another PR to fix this)

Thanks for the CI noticed some issue :

FAILED t/unit/test_services.py::test_Service::test_wait_first__propagates_exceptions - RuntimeError: Event loop is closed

I will take a look later, I believe there is a not pin dependency issue maybe related to pytest-asyncio if used.

I've re-read this MR several times and I'm still baffled as to why this test is failing:

 =================================== FAILURES ===================================
_____________ test_Service.test_wait_first__propagates_exceptions ______________

self = <t.unit.test_services.test_Service object at 0x7f2d2cd492d0>

    @pytest.mark.asyncio
    async def test_wait_first__propagates_exceptions(self, *, service):
        exc = KeyError("foo")
        m1 = Mock()
        m1.done.return_value = True
        m1.exception.return_value = exc
        m1.result.side_effect = exc
        with patch("asyncio.wait", AsyncMock()) as wait:
            wait.return_value = ((m1,), ())
            with pytest.raises(KeyError):
>               await service.wait_first(asyncio.sleep(5), timeout=5)

t/unit/test_services.py:629: 

I'll need to look around more. Sorry that such a simple change turned into this much of an inconvenience. 🤦‍♂️

No pb !

I strongly believe fixing pytest-asyncio in test to 0.21.1 will fix the issue related to pytest-dev/pytest-asyncio#706

EDIT:

I ran tests locally and got issue with the test test_secs_for_next_with_tz due to missing timezone "US/Pacific" but I'm not sure if the timezone source is Python internal or related to computer setup.

pytest-asyncio is having some issues right now, so pinning is the right move for now. LGTM!
