Conversation opened from contacts but contacts permission denied

[daniele-athome]

Some users have found a way to start a conversation directly from contacts, but without allowing Kontalk to read contacts. This is probably going through "send message" action using the smsto schema. There isn't a safe way to fix this other than asking for permission first (if the user denied it, it would be pointless to ask again) or show a warning toast and abort.
