Add optional message to expectElement and expectNoElement

[amyrlam]

• add message to options hash, so can identify expectElement or expectNoElement test with a custom name, similar to assert.ok(find('something'), 'my custom test name here')
• updated ember due to to error message on ember test:

Future versions of Ember CLI will not support v4.2.3. Please update to Node 0.12 or io.js.
version: 1.13.8
Invalid watchman found, version: [4.4.0] did not satisfy [^3.0.0], falling back to NodeWatcher.

• make buildMessage into a helper function
• extract test helpers to be DRY

I get a weird Travis error message that I'm not sure how to debug?

https://travis-ci.org/201-created/ember-cli-acceptance-test-helpers/jobs/112355419

No output has been received in the last 10 minutes, this potentially indicates a stalled build or something wrong with the build itself.
The build has been terminated

hmm, could be this jQuery/Ember CLI incompatibility? Since bower.json says 1.11 is okay, you could try removing the ^ and seeing if that fixes the builds on Travis.
