Don’t Inject jQuery UI CSS all over admin

Hello,

The CSS asset wp-content/plugins/ap-custom-testimonial/css/jquery-ui.css?ver=4.9.5 is enqueued all over the admin area, which breaks many other plugin’s style.

Could you please refactor to enqueue only to the plugin’s own page? Currently you have

add_action('admin_enqueue_scripts', array($this, 'apct_register_admin_assets'));

You just need to delete the line and modify apct_add_plugin_menu like this.

        /** On New Plugin Menu */
        function apct_add_plugin_menu() {
			// Store the page references in an array
			$pages = [];
            $pages[] = add_menu_page('AP Custom Testimonial', 'AP Custom<br/>Testimonial', 'manage_options', 'apct-admin', array($this, 'apct_main_page'), 'dashicons-id');
            $pages[] = add_submenu_page('apct-admin', 'Testimonial Setting', 'Settings', 'manage_options', 'apct-admin', array($this, 'apct_main_page'));
            $pages[] = add_submenu_page('null', 'Create Testimonial', 'Create Testimonial', 'manage_options', 'apct_testimonial_create', array($this, 'apct_testimonial_create'));
            $pages[] = add_submenu_page('null', 'Edit Testimonial', 'Edit Testimonial', 'manage_options', 'apct_testimonial_edit', array($this, 'apct_testimonial_edit'));
			$pages[] = add_submenu_page('null', 'View Testimonial', 'View Testimonial', 'manage_options', 'apct_testimonial_view', array($this, 'apct_testimonial_view'));
			// Loop over the array and enqueue the scripts
			foreach ( $pages as $page ) {
				add_action( 'admin_print_styles-' . $page, array( $this, 'apct_register_admin_assets' ) );
			}
        }

If you are on GitHub, I can send a PR.
