[BUGFIX Release]fix mocha blueprint service test filename

[sly7-7]

Maybe this pr is incomplete, or I could add test in someway (even if this looks to be tested here: https://github.com/emberjs/ember.js/blob/master/node-tests/blueprints/service-test.js#L180,

but when I'm doing
ember g service blah, it gives the results

installing service
  create app/pods/blah/service.js
installing service-test
  create tests/unit/pods/blah/service-test-test.js

Maybe all the test's blueprints filename should be rename 'test.js' ? In that case tell me, and I could complete this pr

@sly7-7 could you add a test similar to https://github.com/emberjs/ember.js/blob/master/node-tests/blueprints/service-test.js#L170-L184 to verify that everything works as planned?

@sly7-7 can you address @Turbo87 feedback?

[sly7-7]

@stefanpenner @Turbo87 Will do that, sorry for the delay, I was on vacation.

@stefanpenner @Turbo87 Should be good now. Out of curiosity, are those tests running on travis ?
