Not all deprecations flushed

The number of deprecations flushed doesn't match the number reported by the Ember inspector

``` json
window.deprecationWorkflow = window.deprecationWorkflow || {};
window.deprecationWorkflow.config = {
workflow: [
{ handler: "silence", matchMessage: "Ember.Handlebars.helper is deprecated, please refactor to Ember.Helper.helper" },
{ handler: "silence", matchMessage: "Using Ember.Handlebars.makeBoundHelper is deprecated. Please refactor to using `Ember.Helper.helper`." },
{ handler: "silence", matchMessage: "Ember.create is deprecated in favor of Object.create" }
]
};
```


I also get this same set each time I run deprecationWorkflow.flushDeprecations() in the browser console.
