Fastboot initial title render

A repost of #43. The title in the html payload is the initial state and not the final state.

That’s correct @Ravenstine but yes it does depend on also using ember-cli-head (and adding setTitle to your route which then sets the title on the headData service.

If you don’t use ember-cli-head then perhaps you’d have to use the method they use to affect what’s in the head - the -in-element helper/component, which seems to be private/undocumented. See here: https://github.com/ronco/ember-cli-head/blob/master/addon/templates/components/head-layout.hbs

I don’t feel quite sure enough about how best to fix this but I believe I’ve identified the problem.

In document-title.js, collectTitleTokens ultimately calls setTitle when it reaches a route with title set. However, it calls the router’s setTitle, which is set when Router is reopened lower down in that module, not the route’s setTitle. I added

  if(self.setTitle && typeof self.setTitle === 'function') {
    self.setTitle(finalTitle);
  }

right before the call to self.router.setTitle and it solved the problem, though perhaps there’s some better option? Please advise and I’ll be happy to submit a pull request.
