Minor, don't show references in diffusion if there isn't any

Browse source 
Summary:
When there are no other references (and there will be none ususally,
if D2891 is accepted), we would show "References:" with empty contents.

Avoid that by testing for empty output after applying stupid filtering.

Test Plan: Looked in a standard repository with no special refs.
