CB-8139 WP8. Fix callback for plugins with native ui (capture,
contactPicker, etc)
https://issues.apache.org/jira/browse/CB-8139
Unload event could not be used to detect when CordovaView is not used
anymore. For example, this event is triggered when we execute command that
shows some native elements on new page and then we return back. In this case
Unloaded event is called but, but control state is preserved and we should
continue to use that Cordova view instance. Same happens when app is
deactivated and then activated again (switch between apps)
This commit changes the following:
1. Allows command instances to be garbage collected => fixes corresponding
memory leak so that NativeExecution is no more required to call DetachHandlers
for each command. This fixes CB-8139.
2. Use Loaded and Unloaded events to add/remove handlers for native events;
this makes it possible for GC to destroy CordovaView when it is not required
anymore
