hanami: --help options does not work correctly for some subcommands

hanami new --help, instead of describing available options, prints

ERROR: "hanami new" was called with no arguments
Usage: "hanami new APPLICATION_NAME"

This discovery made me try the --help option for all other subcommands (at least those listed by hanami help). This way I found a bug

• hanami db --help
• hanami destroy --help
• hanami generate --help

All these commands print

Usage:
  hanami help [COMMAND]

Describe subcommands or one specific subcommand

which is help for hanami help, not for the respective subcommands.

(ADDED LATER)

Help for sub-subcommands prints misleading usage synopsis: e.g. hanami db create --help prints

Usage:
  hanami create

instead of expected

Usage:
  hanami db create
