Run matrix-bot-meowlnir after the homeserver roles

Unlike the other bots, Meowlnir's ensure-matrix-users-created tasks
may need to restart the homeserver so that it picks up Meowlnir's
appservice registration. That only helps once the homeserver's
configuration has been brought up to date by its own role, so the
meowlnir role must come after it.
