Fix crashing and flaky tests in LayoutTests/fast/events/ios. One of the main causes of our crashes is that zooming and keyboard callbacks that have been set by previous tests are not cleared before running the next test, so code from the previous test may be executed during the next test if the test does not set the callback to something else. This causes us to access the previous deallocated UIScriptController and crash.
