Introduce a setting for auto catching exceptions when calling JS method native

[vtrifonov]

We need a setting to enable and disable catching exceptions when calling the callJSMethodNative method. If enabled those exceptions will be caught an logged without propagating them.
The default value of that setting is false, so if such an error occurs it won't be caught and if not handled somewhere else will crash the application.
The flag is disabled by default, so if you want to enable it you should add in your app/package.json file this:

{
	...
	"discardUncaughtJsExceptions": true
}
