`aio rt <any-subcommand-or-none> --help` doesn't print the list of subcommands available

[iivvaannxx]

Expected Behaviour

The command prints the subcommands available under the aio rt namespace when invoking with --help flag.

Actual Behaviour

When using --help in aio rt or aio rt <subcommand> the list of subcommands is not printed. This does not happen if using aio runtime, or any other command like aio app for example.

Steps to Reproduce

1. Run aio rt. This prints:

   aio rt              
   Execute runtime commands
   
   USAGE
     $ aio runtime [--cert] [--key] [--apiversion] [--apihost] [-u] [-i] [--debug <value>] [-v] [--version] [--help]
   
   FLAGS
     -i, --insecure   bypass certificate check
     -u, --auth       whisk auth
     -v, --verbose    Verbose output
     --apihost        whisk API host
     --apiversion     whisk API version
     --cert           client cert
     --debug=<value>  Debug level output
     --help           Show help
     --key            client key
     --version        Show version
   
   DESCRIPTION
     Execute runtime commands
   
   ALIASES
     $ aio rt
   
   TOPICS
     runtime action      Manage your actions
     runtime activation  Manage your activations
     runtime api         Manage your api routes
     runtime deploy      The Runtime Deployment Tool
     runtime namespace   Manage your namespaces
     runtime package     Manage your packages
     runtime property    Execute property commands
     runtime rule        Manage your rules
     runtime trigger     Manage your triggers
   
   COMMANDS
     runtime action      Manage your actions
     runtime activation  Manage your activations
     runtime api         Manage your api routes
     runtime deploy      The Runtime Deployment Tool
     runtime namespace   Manage your namespaces
     runtime package     Manage your packages
     runtime property    Execute property commands
     runtime rule        Manage your rules
     runtime trigger     Manage your triggers
   

2. Compare with aio rt --help. This prints:

    aio rt --help       
    Execute runtime commands
    
    USAGE
      $ aio rt [--cert] [--key] [--apiversion] [--apihost] [-u] [-i] [--debug <value>] [-v] [--version] [--help]
    
    FLAGS
      -i, --insecure   bypass certificate check
      -u, --auth       whisk auth
      -v, --verbose    Verbose output
      --apihost        whisk API host
      --apiversion     whisk API version
      --cert           client cert
      --debug=<value>  Debug level output
      --help           Show help
      --key            client key
      --version        Show version
    
    DESCRIPTION
      Execute runtime commands
    
    ALIASES
      $ aio rt
   

3. See how the TOPICS and COMMANDS are missing when using --help. This also happens under subcommands of aio rt.
