Move blueprint-test to node-tests folder

[trabus]

To go with a more consistent structure for the tests, we should move the generated blueprint-nodetest.js in the blueprint-test blueprint to the node-tests folder.

• create node-tests folder in blueprint-test blueprint files
• change naming scheme from blueprint-nodetest.js to [blueprintname]-test.js
• change .npmignore to ignore node-tests folder
• change test runner to look into node-tests folder instead of looking for -nodetest
• move blueprint-tests in ember-cli-legacy-blueprints to node-tests folder

Reopened for the last item on the checklist (moving the files around in ember-cli-legacy-blueprints).

Working on that now. Thanks for reopening.

I have one more change, the blueprint tests were being generated in node-tests/blueprints/blueprintname/blueprintname-test.js, I'm moving it to node-tests/blueprints/blueprintname-test.js.

@rwjblue One thing I've found a bit annoying is blueprints with -test become -test-test, but it's only a minor annoyance.

LOL, that is kinda funny, but I think in its own way it makes sense...

@trabus I think since the test blueprints are also tested by the main blueprints we can just move the test blueprint tests into the main blueprint tests file.

closing this in favor of ember-cli/ember-cli-legacy-blueprints#2
