Wrong ID used to identify users

We were poking around the code and is seems that the modules uses wrong ID for loading GigyaUser object.

Bit of context:
.../gigya/gigya.module:134

  // If the user is logged in then attach the Gigya object to the
  // user object.
  if (user_is_logged_in()) {
    global $user;

    // Attach the Gigya object to the user object.
    GigyaUser::load($user);

calls

  public static function load(&$account) {
    // Attache to user if the user is logged in.
    $account->gigya = (isset($account->uid) ? new GigyaUser($account->uid) : NULL);
  }

Where $account->uid is just Drupal ID. But it should be Gigya ID which looks something like "17e4399180968c8bdadd64b7a74a4cfc" and this is available in $_SESSION['gigya_raas_uid']

More details to be considered:
* we are using RaaS only - maybe this is not true for non-RaaS configs
* It's probably on more places - gigya.module:134 is just first I found while creating the issue.
