mod_mam: Don't store any groupchat messages The intent was to not store MUC groupchat messages, which are sent from the MUC to local full JIDs, while allowing for potential future account based group chat. However, since this function handles messages in both directions and outgoing MUC messages are sent to the bare room JID, those were stored.
