org-gnus.el: Handle `gnus-summary-mode' and `gnus-article-mode' separately.

Use `gnus-summary-article-header' function when in gnus-summary-mode.
This way the article doesn't get displayed unnecessarily.  We don't use
this function in the gnus-article-mode because it is not reliable.

Thanks to Leo for this suggestion.
