Degrade: Fix smart sync/smart tag

This was broken in b2bd91c, which updated the manifest after it had
been overridden, which made it fall back to the original file (and
not the one from the manifest server).

This builds on 0766900 and overrides the manifest by the one
downloaded from the manifest server completely.
