Fix issue of not setting metadata correctly for generated docs

Fix issue of not setting metadata correctly for generated docs

Removed if clause does not return any html file, causing setmeta
to not run which in turn causes people to see cached versions of
the generated documents instead of the latest generated documents.

This is a quick fix in order to unblock Brady.
