Allow subscriber to be collected if MessagingCenter is the only reference to it (#617)
* Repro
* Make messaging center callbacks weak references
* Preserve attribute
* Fix test method name
* Watch for collection of actual delegate target instead of wrapper delegate
* Preserve the original platform instance when changing main page
* Better tests for lambda situations
* Update tests, make callback target a weakreference if it's the subscriber
* Ensure old Platform MessagingCenter subs are gone before creating new Platform
