You need to modify the code to get them: that's probably an omission
(ngz will probably respond in much more detail than I can). They are
only cosmetic of course, but if you have to have them, you can try
adding them in org-beamer-template around line 880:

	       (concat (plist-get info :latex-header)
		       "\n"                                  
		       (plist-get info :latex-header-extra)
		       "\n"
		       (plist-get info :beamer-header-extra)
		       "\n")))

The problem with this is that the newlines are added even if the
various items are empty, so you may end up with more newlines than
are necessary.
