Subject: [PATCH] feat(ngMock): destroy $rootScope after each test

Previously $rootScope would be new for each test, but old $rootScopes would never be destroyed.
Now that we are able to destroy the $rootScope, doing so provides an opportunity for code to clean
up things like long-lived event handlers between tests.
