re-run pr-opensuse15-py3

@lukasraska Please add your integration tests. I will take a look at making them less flaky.

@dwoz Thanks for looking into this, I've pushed them and rebased to latest master. From my tries, the setUpClass method can sometimes raise Empty for no apparent reason (some environments work almost all the time, some raise it almost every time). Also I don't know if the Win test failures are related to this PR, but running just these tests is working fine on my win-server setup.

It also might be worth noting, before the change in logging, these tests using multithreaded Queue were completely failing on Win and OSX (they worked when print was put strategically, as I mentioned on SaltConf).

If you can think of how to make them more successful, tests.integration.modules.test_event can reuse the same mixin and can be re-enabled.

That's interesting, and hints at a race condition. It may be something else, but print involves a pretty hefty wait on that thread along with the system call(s). You should check if a time.sleep(1) accomplishes the same thing. That would be a strong indication that we're running into a race condition. If it's only the print that works, though, that's pretty confusing.

@lukasraska are you still interested in pushing this over the finish line?
