[D6] Modules that implement hook_composer_json_alter() should trigger a composer.json file rebuild when enabled / disabled

Follow-up to #2297405: Modules that implement hook_composer_json_alter() should trigger a composer.json file rebuild when enabled / disabled

Modules that implement hook_composer_json_alter() generally modify the consolidated composer.json file in some way, so enabling / disabling them should trigger a rebuild when the modules implementing them are enabled / disabled.
