Title: Remove isTop in favor of a downstream implementation.

Ember has been updated to provide its own `isTop` (other modifications were needed also) in https://github.com/emberjs/ember.js/pull/9585.

`isTop` doesn't really seem like a fundamental HTMLBars concern (is only needed to support the current implementation of the `{{outlet}}` helper).
