metismenu: toggle doesn't work when no sub-menu is present

Hi, I found out that toggle doesn’t work right with items that don’t have sub-menus.

For example:

<ul id="menu">
    <li><a href="#/page1">Page 1</a>
        <ul>
            <li><a href="#/sub-page1">Sub-page </a></li>
            <li><a href="#/sub-page2">Sub-page 2</a></li>
        </ul>
    </li>
    <li><a href="#/page2">Page 2</a></li>
</ul>

The problem is line 37 in the code:

$this.find("li").has("ul").children("a").on("click" + "." + pluginName, function(e) ...

Everything works fine when I remove .has("ul") from the code.

The thing is I’m working with angular and not using direct links but routing based on my location, so even when the link doesn’t have a sub-menu, it still doesn’t go to a new page but should toggle the other menus.
