Remove remaining jQuery from View tests

Now that #3003 is merged, we need an easy way for alternative View implementations to run against our View conformance test. This pulls jQuery out of the View tests except in for checking `view.$el instanceof Backbone.$` (which all jQuery-like apis should support).

We can and should get rid of the click shim as soon as that phantom bug gets fixed. Either that or we use a different test runner like Karma that actually tests on real browsers.
