This test fails for me locally. I am not sure it needs to exist either, as it just seems to be the other test, but with shutting down the server. So perhaps just remove this, and remove the state.kill modification in apps/email/test/marionette/lib/servers/fakeimap.js too. if you do rework this one to run, then renaming it to something more descriptive as relating to the next/previous would be good.
