t helper is broken with glimmer (1.13 compatibility)

[blimmer]

The helper.js implementation appears to be incompatible with the newly released Ember 1.13 helpers.

There are several errors associated with these changes, it seems:

1. Container moved in environment
   This patch fixes this part:

export default function t(params, hash, options, env) {
  const container = env.data ? env.data.view.container : env.container;
  const i18n = container.lookup('service:i18n');

1. Structure of stream appears to have changed
   The output from the helper appears to be [Object object] once the container lookup passes.
   

Supposedly 1.13 supports non-dasherized helpers, so perhaps the hack to register the helper in the initializer is no longer needed (this would be great for testing).
