Possible issue websocket logic

[basfroman]

Context:

When we run the test tests.e2e_tests.test_commitment.test_commitment_async then the test passes successfully.
But if we run warning logging (use the command pytest -s -vv tests/e2e_tests/test_commitment.py::test_commitment_async) then we see the following messages:

============================================================================================================================================= 1 passed in 43.54s ==============================================================================================================================================

Additional context:

I tried:

1. Running the test with and without async with async_subtensor as sub:
2. Manually running the test in await async_subtensor.initialize() and await async_subtensor.close()
   Always the same result.
