Infinite loop in Routable.unroutePath when initialState is set on a parent Route

[rconnamacher]

Create a Router tree with the following structure:

  App.Router = Ember.Router.extend({
    location: Ember.Location.create({ implementation: 'hash' }),
    enableLogging: true,

    root: Ember.Route.extend({
      initialState: 'stateOne',

      states: {
        stateOne: Ember.Route.extend({
          route: '/dashboard',
        }),
        stateTwo: Ember.Route.extend({
          route: '/state-two',
        }),
        stateThree: Ember.Route.extend({
          route: '/state-three',
        }),
      }          
    })
  })

When using the back button to return to a previous state (other than the default routeOne state), an infinite loop is triggered in Routable.unroutePath.

This happens because unroutePath searches recursively through a state's parents and since subDir has an initialState set, that state (stateOne) is being entered automatically when subDir is entered. stateOne then recursively returns to its parent, which then bounces back to stateOne again.

Test case (links directly to ember-latest.js on github): http://jsfiddle.net/TS5TZ/1/
Warning: can cause a crash in both Safari and Firefox on my system. Chrome handles it without crashing.

I just fixed this. Thanks for pointing it out.
