cccca8a77f test: Avoid logging error when logging error (MarcoFalke)
Pull request description:
Currently a logging error in the form of `--- Logging error ---` happens when an error is logged in the `_on_data` helper.
Fix it by properly logging the error.
Also, treat pylint errors as errors, to avoid this problem in the future.
Can be tested by running `p2p_addrv2_relay.py` with the following example diff:
```diff
