statusline: update status only when necessary

Browse source 
Update statusline only when changed to reduce cpu usage.

commit 2512c0403f ("statusline: implement per-account status") updates
the status irrespective of whether the statusline changed or not. This
can lead to high cpu usage that can be avoided.
