Subject: [PATCH] ZXingScannerViewRenderer was causing the app to crash if the
 view was inside a ContentView

If the `ZXingScannerView` was inside of a `ContentView` instead of a `ContentPage`, the application would crash by throwing a `Java.Lang.NullPointerException`. The `Context` passed to `ZXingScannerViewRenderer` via the constructor was actually a `ContextThemeWrapper` which does not inherit from `Activity`. Therefore when it was cast in the call of the constructor of `ZXingScannerView` in the renderer on Android, a `null` would be passed for a context instead.

Fixes: #943
