LoginWithAmazon: user data is empty if user is still logged in upon startup

[raven-worx]

The user data is empty if user is still logged in when the app starts / plugin is loaded Either the java/jni call doesn't make it to C++ at this time, or the AuthorizationManager.getToken() call doesn't return proper user data.

Needs invesitagtion.

user data wasn't set when the user was already logged in upon startup - fixes #5
