Update grunt-contrib-jasmine
Compatibility with jasmine 2.0

- Jasmine 2.0 doesn't allow you to grab the existing matcher and
  override it, so the matchers that did that had to be re-worked.
- toBe is now a customEqualityTester so:
  - toBe($('.foo'))
  becomes:
  - toEqual($('.foo'))
- toContain was renamed to toContainElement
