    Don't make `help` require auth parameters

    The `help` command was behaving a bit funky. This patch re-orders the
    code a bit so that the `help` command will be parsed at the very
    beginning before running other commands and checks.

    It also allows to get help without downloading/checking schemas and
    without requiring auth credentials (previously required by the schema
    operations).
