Fixes Statusbar tabs and Cleanup

- Fixes statusbar tabs.
Bug: Statusbar used nickname if it was set in roster,
irrelevant to /statusbar chat setting.
Expected behaviour would be using this setting set as "user" to show nickname,
and to show jid with "jid" setting.
Other solution is to give a user control over it with another settings.
- _status_bar_draw_maintext cleaned up, no changes to behaviour
