    relay: Factorize relayJoins usage in initializeChannel and truly fix #74.

    The real error was that queued_users was being defined in the wrong spot (outside of the for loop),
    so the user list would grow larger and larger with every network initialized.

    This reverts parts of the previous commit which weren't actually necessary.

    Mark users as internal at the IrcUser level (attempt to fix #74)
