Make public to edit commands_objects

When do not use `runCommand`` or `processUpdate`, `$command_object` cannot be updated so cannot run `executeCommand``:
It appears like this:

• create a new Command
• call it by executeCommand
• this command's __construce can be run
• this commans's execute cannot be run
