Subject: [PATCH] statusbar: check if roster exists

We destory the roster in ev_disconnect_cleanup().
Adding a function to test if the roster has been destroyed and testing
for it in the statusbar.

So now when the connection is lost 'Lost connection' is printed in all
open windows.
We can then reconnect with `/connect accountname`.

Should fix https://github.com/profanity-im/profanity/issues/1083
