Stop the nag notification for enabling texts on Hangouts? Pretty much every time I get a text message, Hangouts gives me an annoying notification asking to handle my text messages (which I don't want to do). Is there a way to disable it?
Turn it on, then go into Hangouts and turn it off.  

Actually I really wanted to write/receive SMS from Hangouts, but it didn't quite work well. Sometimes I could not even reply to the message. So yeah. I disabled it and no nag ever since.
