re-fix alt+tab'bing through tabbed windows

commit 98313bf broke (i'm terribly sorry) this because m_cycling_last stores
the first client in a tabgroup, thus cannot be abused for this purpose.
So we explicitly store a value and btw. do it before sending the focus,
ie. "in time" for sure instead of "for sure™"
