Contining a saved mailing doesn't load included or excluded previous mailing recipients

This is the first Recipients selection screen and is simply an issue with correctly populating the $defaults variable. Minimal fix is below:

diff --git a/sites/all/modules/civicrm/CRM/Mailing/Form/Group.php b/sites/all/modules/civicrm/CRM/Mailing/Form/Group.php
index 51f013d..45e83e6 100644
