    ontology: Set domain index on nie:contentCreated for nmo:Message
    
    This is needed in order to optimize queries for mixed sent/received
    nmo:Messages. This becomes a bottleneck when making polari use
    tracker-miner-chatlog [1] information to fetch backlog from channels.
    
    nie:contentCreated will be contained by every nmo:Message, so this
    index allows us to perform quick queries even with a massive amount
    of per-channel messages.
