Closes angular#14204 BREAKING CHANGE: $animate.cancel(runner) now rejects the underlying promise and calls the catch() handler on the runner returned by $animate functions (enter, leave, move, addClass, removeClass, setClass, animate). Previously it would resolve the promise as if the animation had ended successfully. Example: ```js var runner = $animate.addClass('red'); runner.then(function() { console.log('success')}); runner.catch(function() { console.log('cancelled')}); runner.cancel(); ``` Pre-1.7.0, this logs 'success', 1.7.0 and later it logs 'cancelled'. To migrate, add a catch() handler to your animation runners.

Isn't it enough to check that runner.cancel is called, since runner.cancel appears to have comprehensive tests of its own?

Hm, that's right, just the runner tests don't test with actual DOM elements and not with the $animate functions. Your call whether it should be simplified.

Other information:
There is another aspect to this problem that is not fixed by this PR:
2. Cancelling css animations should immediately abort the animation and set the DOM / css to its final state. This is currently broken in FF and IE11 (at least), see https://bugzilla.mozilla.org/show_bug.cgi?id=1425014. This must be tested with e2e test. Fixing this is not a BC.
