Civimember Roles Sync module erasing user data

civicrm_member_roles module is listening to the Drupal hook_login() and then attempting to perform its synschronisation. In the course of this, it saves the Drupal user object but it does so in a way where this object might be stale or missing certain data — and thus erases user data.

The solution to this is to force a reload of the user object before attempting to save it. Please see attached patch.
