Flaky Integration Test(s)

[reedsa]

What happened?

Every now and then we get failures in CI from tests that appear to flake. Investigate and fix the flakiness.

Running with pytest-flakefinder shows exactly where things break down. I found that running all tests with in TestGoEthereumAsyncEthModuleTest with the flakefinder, tests/integration/go_ethereum/test_goethereum_ws/test_async_ctx_manager_w3.py::TestGoEthereumAsyncEthModuleTest::test_eth_modify_transaction passes the first 30ish times or so but then hangs for a bit and starts failing.

It appears that the request ID is not being matched with the cached response properly, if the response even exists. The test itself modifies the transaction but I'm not sure if it would effectively overwrite the original transaction in the cache. Perhaps this is why the IDs get messed up or the queue is not the expected size. Still digging.

After further investigation, it seems that slowing down the test with sleep or even using wait_for_transaction_receipt will cause the failure to happen on the 14th run.

Added @flaky_geth_dev_mining but it isn't working either.

Fill this section in if you know how this could or should be fixed

Will need to investigate. Could be some context somewhere that's getting reused, like an object that should be copied instead of assigned.

We discussed changing the websocket provider so that replace_transaction handles the transaction properly. The original request should be removed from the cache so that there is no expectation for that response to come back.
