If the intention of the new "auto expansion" feature is to reduce HTTP calls to the Stormpath API: you will also need to pass the opted-in expansions to the `getAccount()` call.  Doing so will place the expanded resources in the cache.  As written your code in `expandAcount()` will trigger new HTTP requests for those resources because they aren't in the cache yet.  Note: this is only applicable to expansions that are not collections.  For expansions that are collections you will always need to incur a second HTTP request.
