AccordionItem: click on title link does not work

[simonihmig]

Clicking on the <a> does not expand the item, but follows the href. See http://www.ember-bootstrap.com/#/components/accordion.

Probably introduced with #307. An e.preventDefault() in the click handler should do the trick. Should be covered by a test.

@dajk wanna have a look?

Ah, yes sure.. I'll do that.

I think this might be related; accordions seem to be broken on iOS 10 (tried both Safari and Chrome) - could be something to do with the missing preventDefault() in the handler and click propagation.

Oh and by broken I mean the accordions appear fine, but clicking on them doesn't open the accordion item. Clicking on the title link follows the href, however
