Also shuts down `Broker`, which, before this PR, we did start in `start()` but relied on the fixture to stop. Do it a bit earlier so that, after `NeonEnv.stop()` returns, there are no child processes using `repo_dir`. Also, drive-by-fixes inverted logic around `ps_assert_metric_no_errors`, missed during https://github.com/neondatabase/neon/pull/6295 --------- Co-authored-by: Alexander Bayandin <alexander@neon.tech>
