Need help with Android sharing intents

I fat fingered my phone this morning and hit "always" button in the sharing menu on my Nexus 5. Now every time I try to share something it defaults to Google Hangouts. From what I can tell the usual way to resolve this is to go to settings>apps>Hangouts and hit the clear defaults button, however on my phone Hangouts says "no defaults set" and the clear defaults button is grayed out and unavailable. Does anyone know another way to reset the intents/defaults in Kitkat?
