    TelepathyClient: use polari for IRC channels
    
    polari is the GNOME app for IRC, empathy is for everything else
    So prefer polari to empathy for IRC channels. We don't need
    to check that either exists (even though polari is not a core
    app) because mission control tries every handler if the preferred
    one fails.
    Depends on bug 745418 for polari to be mission control activatable.
