Subject: [PATCH] Don't perform roster push for non-local contacts in
 mod_shared_roster

If group have member with jid from external server we tried to make
mod_roster sent roster push to it, and it sometimes didn't like to get
bogus data like that, so let's check if it's local user before doing this.
