Use correct bound helper params

Bound helpers only get params and hash (the first two args).

[rwjblue]

You should likely put the args in comments (otherwise the JSHint tests will blow up after generating):

export function <%= camelizedModuleName %>(/* params, hash, options, env */) {
}

And I think that the generate tests will also need to be updated.

@rwjblue I'm a little confused, all the helpers I see in core have 4 params. Can you point me to some documentation on this?

[rwjblue]

Helpers in core are not using Ember.HTMLBars.makeBoundHelper, since they are not bound helpers.

Documentation is here:

@rwjblue Does it look okay now?

I think this will make the default helper test not pass: https://github.com/ember-cli/ember-cli/blob/master/blueprints/helper-test/files/tests/unit/helpers/__name__-test.js

@kimroen - You are correct, mind submitting a PR?

[kimroen]

@rwjblue Done :)
