Using this addon in an acceptance test causes "Assertion after the final assert.async was resolved" errors

There is a known issue about this w/ qunit v2 in ember apps (i.e. ember-cli-qunit 3.x), but for some reason, the suggested workarounds are not working in the one app I've seen this issue in. See ember-cli/ember-cli-qunit#162 (comment) Don't know if that's a sign of a fundamental issue w/ this addon, or that app, the way I tried to do the workaround, or a symptom of a broader problem.

Until that issue is resolved, we should try other workarounds (downgrade ember-cli-qunit version in that app), try the addon in other apps, and document the issue and any successful workarounds in the README.

Closing this b/c I'm no longer getting "Assertion after the final assert.async was resolved" errors, but I am having other errors w/ Acceptance tests, see #27 and #28.
