Ember.testing is not allowed in modules scope

Rule name: no-ember-testing-in-module-scope

Since ember-cli-qunit@4.1.0 / ember-qunit@3.0.0, Ember.testing is only set to true while a test is executing instead of all the time. Also, Ember.testing is a getter/setter in Ember and destructuring will only read its value at the time of destructuring. emberjs/ember-test-helpers#227
