Fixed obscure miscalculation when a client is closed.

This crops up whenever you just switched from tab # N+1 to tab # N
and close current tab. unmanage() first decreases lastsel
(so it becomes N) then erroneously tests it against sel and focuses first tab
instead. One can see that focus() would never set lastsel == sel,
so I took liberty to fix this annoying behaviour which happens to frequently
with newposition = 0 and npisrelative = True settings.
