SMS: A blocked number's SMS will come through if the conversation is deleted
I am on PureOS/Chatty 0.6.4
If I block a contact (in this case, it was the Visual Voicemail number since I don't want two notifications for a VVM), I have to keep a conversation archived for it to stay blocked. If I delete the archived conversation, I will get a notification and an SMS showing up in Chatty the next time the blocked contact sends me an SMS.
