NullPointer in AuthenticationApi.login

[dcestnik]

In versions >= 2.10.0 any call to the method AuthenticationApi.login will fail with a null pointer exception. Applying the below patch to eg-01-java-jwt will reproduce the issue. I believe it is caused by this which was introduced in 2.10.0. Please advise if there is a work around. We are needing to call this method in order to fetch the login accounts baseUrl in our application.

@dcestnik Authentication class is deprecated (although we need to document this fact better). Please use ApiClient.getUserInfo instead to get the list of accounts like in the JWT example: https://github.com/docusign/eg-01-java-jwt/blob/master/src/main/java/com/docusign/example/jwt/ExampleBase.java#L71
