Do not print contact status when contact is not-in-list
= phenomenon Contact status of not-in-list contacts is printed (it will always be offline).
= background analysis Gajim prints contact-status-line of "contact is offline" for not-in-list contacts each time user goes offline; on the contrary, Gajim does not print contact-status-line of "contact is offline" for offline contacts each time user goes offline.
= Steps to reproduce
- Open a chat with an offline contact from roster.
- Open a chat with a contact not in roster.
- Log on (online).
- Log out (offline).
- Repeat steps 3 and 4.
= implementation recommendation Make Gajim to behave with not-in-list contacts like it does with offline contacts.
