Fails with ember-concurrency#277 and Ember canary

[gitKrystan]

I'm trying to get our tests passing on Ember canary and ran into the issue you described in machty/ember-concurrency#279 (thanks for tracking that down, by the way).

I pointed our ember-try 'canary' scenario at machty/ember-concurrency#277, but now I'm running into this assertion from ember-concurrency-test-waiter:

ember-concurrency-test-waiter/addon/with-test-waiter.js

Line 12 in 8d302fb

assert("withTestWaiter() will only work with ember-concurrency >=0.7.19 -- please upgrade", taskProperty.taskFn);

Right, thanks for the report @gitKrystan -- that PR is definitely going to break ember-concurrency-test-waiter (not just the compatibility check, but the whole mechanism to install a test waiter will no longer work!). I'll work on a solution, and hopefully get some help!
