Divert to call `gnus-activate-group' with the SCAN argument set

Browse source 
* lisp/gnus/gnus-group.el (gnus-group-get-new-news-this-group):
Divert to call `gnus-activate-group' with the SCAN argument set,
if request-group-scan is not defined for the backend.  Ensure that
the server is open when calling `gnus-request-group-scan'
(bug#22649).
