Remove unused `didReload` hook.
Remove old-tests.
Update `ember-dev` to (b0b12c4).

Updates `ember-dev` to (b0b12c4) which includes the following changes:

* Will not attempt to `unshallow` a full git repo
* Makes default test suite (packages only) run with features enabled and
  disabled.
* Fixes bug where the wrong Project name is used in the auto-generated
  CHANGELOG.
* Allows overriding the build type. (Simply set `ENV['BUILD_TYPE']='canary'`)
* Add `ember:generate_static_test_site` task to create a static HTML
  file for running the test suite.
* Add custom test results gathering for use in cross-browser testing.
* Make sure that the test file being used in the `Assetfile` is prefixed
  with the proper dasherized project name (prior to this Ember Data
  tests were still named `ember-tests.js` and now they will be
  `ember-data-tests.js`).
* Fixes issue where local `rake test` runs would attempt to perform git
  operations (`checkout` and `cherry-pick`). Now git operations will
  only be attempted if `ENV['CI']=true`.

Generate static site tests.

This will publish a ember-tests.html static test site along with the
builds. This makes it extremely simple to test the latest
canary/beta/release builds on various devices. It is also critical to
the cross-browser testing that we have been working on.

Update to Ember 1.1.0 (and fix tests).

Updated Gemfile to use 1.1.0 (latest stable version of Ember).

Ember 1.1.0 does not allow items to be re-registered on a container if
they have already been looked up. This change was made
[here](https://github.com/emberjs/ember.js/commit/b8b9878bcf6517ee2b25b0e309f2a5bf5e3ff7d1).

This refactors the tests for `DS.Store#push` so that it does not throw
an errors with 1.1.0.
