Change Application.cfc method "onApplicationStop" to "onApplicationEnd" in examples

[jjannek]

The ACF/Railo/Lucee internal Application.cfc function is called onApplicationEnd instead of onApplicationStop. I suggest to use it. This way there are also no errors if calling the method manually after applicationStop() during a re-init or manual stop of the example apps. There is no manual call of the method required.

Hey @jjannek

I appreciate the pull request. Before I merge it I want to ensure all the existing tests pass, and to do that I need to get a proper CF environment set up again, which might take me a few days since I'm travelling.
