fix(mocks): remove usage of $animate.flushNext in favour of queing
The flushNext method of testing is difficult and highly coupled with the behavior of ngAnimate's $animate workflow. It is much better instead to just queue all $animate animation calls into a queue collection which is available on the $animate service when mock.animate is included as a module within test code.
