fix($animate): applyStyles from options on leave

[PatrickJS]

missing [options] API that should either be removed from the docs or added in the code

@param {object=} options an optional collection of options that will be applied to the element.

the tests weren't working for this feature

      $animate.leave(element, 'off', {
        to: { color: 'blue' }
      });
      assertColor('blue'); //nothing should happen the element is gone anyway

you can view the docs here https://ng-click.com/$animate#leave

@gdi2290 - thanks for this. Could you provide a unit test that checks that the options argument has an effect?
@matsko - can you verify that this is correct and merge?

[PatrickJS]

@petebacondarwin I fixed the test and pulled in latest changed from master

// previously 
$animate.leave(element, 'off', {
  to: { color: 'blue' }
});
// should be
$animate.leave(element, {
  to: { color: 'yellow' }
});

the problem was that the test had too many arguments (due to copy/paste of $animate.removeClass)

[PatrickJS]

@petebacondarwin can you remove the [needs: test] tag. The PR is ready for merge and really should have made 1.3.4 release unless I'm missing something. $animate still is broken for leave animation

@gdi2290 - thanks for the fix to the test. I have removed the tag. There were changes to the CLA process a few months ago.
