Remove @ember/runloop in test blueprints

[mkszepp]

After removing all @ember/runloop from my app i have discovered that new test blueprints are bringing again the lint warnings.

By using the command ember g instance-initializer my-init or also ember g initializer my-init (maybe also other blueprints) we are getting non recommended codes inside the app.

The blueprints should be refactored, so that they don't bring anymore @ember/runloop.
