Don't use summary window to visit group buffer (bugfix)

Browse source 
* lisp/gnus/gnus-sum.el (gnus-summary-jump-to-group): Make sure that
the window to open the group buffer doesn't visit the summary buffer.
This fixes a bug: `gnus-summary-next-article' sometimes causes an error
by trying to select nonexistent summary window.
