fix($animate): accept unwrapped DOM elements as inputs for enter + move

Prior to this fix the $animate.enter() and $animate.move() events caused
an error when a parent or after element was provided that was not
already wrapped as a jqLite element. This patch ensures that both
wrapped and unwrapped DOM nodes are allowed.

Closes #11848
