i18n not working

Hi, I realised the translations were not working, and after some investigation I discovered that plugin's translations should not be loaded during the plugins_loaded action. This because prevents other language-related plugins from properly hooking into the load_textdomain() function, so load_plugin_textdomain() should be triggered during init action. reference

the change is needed here: $this->loader->add_action( 'plugins_loaded', $plugin_i18n, 'load_plugin_textdomain' );

must be changed in this way: $this->loader->add_action( 'init', $plugin_i18n, 'load_plugin_textdomain' );

hope it helps

ps. thanks for this useful boiler template!
