jcli help helper does not work with --host argument being passed

[mark-stopka]

Describe the bug
If you try to navigate thru the REST API of Jormungandr --host needs to be passed to indicate the API target, using option --help with --host works just fine, but using help results in following error.

(cardano-jormungandr)[jormungandr@bcdc49f9a6ac /srv/cardano/jormungandr]$ jcli rest v0  help --host http://localhost:3100/api                                                                  
error: The subcommand '--host' wasn't recognized

USAGE:
        jcli rest v0 help <subcommands>...

For more information try --help
(cardano-jormungandr)[jormungandr@bcdc49f9a6ac /srv/cardano/jormungandr]$ 

Mandatory Information

1. jcli --full-version output;

jcli --full-version
jcli 0.9.0-rc1 (master-2715361c, release, linux [x86_64]) - [rustc 1.44.1 (c7087fe00 2020-06-17)]

2. jormungandr --full-version output;

jormungandr --full-version

To Reproduce
Description is pretty clear, but I provide example of using --help option below...

(cardano-jormungandr)[jormungandr@bcdc49f9a6ac /srv/cardano/jormungandr]$ jcli rest v0  --help --host http://localhost:3100/api
jcli-rest-v0 0.9.0-rc1
API version 0

USAGE:
    jcli rest v0 <SUBCOMMAND>

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

SUBCOMMANDS:
    account        Account operations
    block          Block operations
    diagnostic     System diagnostic information
    help           Prints this message or the help of the given subcommand(s)
    leaders        Node leaders operations
    message        Message sending
    network        Network information
    node           Node information
    rewards        Rewards information
    settings       Node settings
    shutdown       Shutdown node
    stake          Stake information
    stake-pool     Stake pool operations
    stake-pools    Stake pools operations
    tip            Blockchain tip information
    utxo           UTXO information
    vote           Vote related operations

Expected behavior
I would expect both help and --help to be treated the same even if --host is passed to jcli.
