    Presence: Only fetch presence for current account.
    
    We were fetching presence of the same list of uris for each account
    instance. Only fetch if account is enabled.
    
    This asks the question: shouldn't we fetch presence only if the uri
    correspond to the account at the presence core level instead of passing
    the list of all uris to all account instances?
