Discard context arg from vwm_win_focus_next()

This can just be derived from the state of the basis window, I think originally
I had intended to implement context switching via this function.

Also changes the implementation to stop comparing against
focused_(shelf,desktop) which prevented doing transitions on invisible
contexts.  It's not usually an issue, but windows can go away at any time, and
we must be able to focus next when they do, even if their context isn't the
visible one.
