Logout bug in android API using kotlin

I think there is a bug in the logout callback, when using it with Kotlin.

The error is:

Caused by: java.lang.IllegalArgumentException: Parameter specified as non-null is null: method kotlin.jvm.internal.Intrinsics.checkParameterIsNotNull, parameter payload
        [...]
        at com.auth0.android.provider.LogoutManager.resume(LogoutManager.java:55)
        at com.auth0.android.provider.WebAuthProvider.resume(WebAuthProvider.java:531)
        at com.auth0.android.provider.AuthenticationActivity.deliverAuthenticationResult(AuthenticationActivity.java:129)
        at com.auth0.android.provider.AuthenticationActivity.onResume(AuthenticationActivity.java:90)
        at android.app.Instrumentation.callActivityOnResume(Instrumentation.java:1446)
        at android.app.Activity.performResume(Activity.java:7939)

It looks like the error is that LogoutManager.resume(LogoutManager.java:55) is called like this
callback.onSuccess(null); but the BaseCallback.void onSuccess(T payload); is specified as non null.

Hey there @ambimi-bpappin!

Can you raise that as a GitHub issue and then share the link to it with us here so we can ping repo maintainers about that? Thanks!
