Bug fixes in some artisan commands

- fix module not found when run `module:migrate`, `module:migrate-rollback` & `module:migrate-reset` without specify the module name.
- if you not specify a module name, we will assume you run it for all modules. This applies to some commands like `module:migrate`, `module:migrate-rollback`, `module:migrate-refresh`, `module:migrate-reset` & `module:seed`.
- if you added `--seed` flag when you running `module:migrate` command, it also will run `module:seed` command.
