Andrew Henry 433dee0314 Update test specs to use Jasmine 3 (#2089)
* Updated Karma and Jasmine versions

* Added DOMObserver class. Supports promise-based testing of DOM changes

Update asynchronous test specs to use promises or done() instead of waitsFor/runs

* Modified ActionCapability to duplicate context object properties as own properties for better object equality comparisons

* Global find + replace to fix syntax issues

* Fixed various issues caused by non-deterministic runtime order of tests in Jasmine 3. Fixed issues caused by changes to determination of object equality

* Addressed review comments

* Resolved merge conflicts with master

* Fixed style errors

* Use spy.calls.count() instead of manually tracking

* MockMoveService provides the same interface as the moveService,
* returning promises where it would normally do so. At it's core,
* it is a jasmine spy object, but it also tracks the promises it
* returns and provides shortcut methods for resolving those promises
* synchronously.
*
* Usage:
*
* ```javascript
* var moveService = new MockMoveService();
*
* // validate is a standard jasmine spy.
* moveService.validate.and.returnValue(true);
* var isValid = moveService.validate(object, parentCandidate);
* expect(isValid).toBe(true);
*
* // perform returns promises and tracks them.
* var whenCopied = jasmine.createSpy('whenCopied');
* moveService.perform(object, parentObject).then(whenCopied);
* expect(whenCopied).not.toHaveBeenCalled();
* moveService.perform.calls.mostRecent().resolve('someArg');
* expect(whenCopied).toHaveBeenCalledWith('someArg');
* ```
