Context is not being reset between test runs

[Turbo87]

  describe('pretty-color integration test', function() {
    setupComponentTest('pretty-color', {
      integration: true
    });

    it('renders with color', function() {
      this.set('name', 'green');
      this.render(Ember.Handlebars.compile(`{{pretty-color name=name}}`));
      expect(Ember.$.trim(this.$().text())).to.equal('Pretty Color: green');
    });

    it('renders a second time without', function() {
      this.render(Ember.Handlebars.compile(`{{pretty-color name=name}}`));
      expect(Ember.$.trim(this.$().text())).to.equal('Pretty Color:');
    });
  });

Expected behavior: the second test should pass since the context on each test is being reset and name should be undefined.

Actual behavior: the name value from the first test bleeds into the second test and results in Pretty Color: green instead.

Thanks to @acburdine for figuring this out! (see TryGhost/Admin#206 (comment))

This seems to have been introduced by v0.9.x, but it not limited to the new testing API.

It seems that this was caused by #89 and #91. Reverting those two commits fixes the issue.

Heh. This is a mocha design issue.

Yes, but one that we can work around if the thing that get/set work on is reset before each test.

Fixed by #111
