Fixes #430. (maybe)
I was not able to reproduce flakiness locally, thus this PR is a best guess.
The test failure suggests that more than three messages were received, even though we only publish 3 messages in the test. This could be due to message re-delivery or because a topic might be shared between tests.
This PR reduces the total wait time in the message callback. It used to be 5 + 5 seconds, which is just the default ACK deadline, thus reducing that to 8 seconds might help. In addition, the test now prints the log output if one of the assertions fail, which will help with debugging, should the flakiness continue.
We could also use auto retries by
flaky
as a last resort, but let's see if we can fix the root cause first.(update: Yet I did this for the unrelated delete schema test, because it's quite often been flaky recently)
