Fix register.json missing fields after bblocks:// URI normalization

Apply _apply_bblocks_uri_refs() at register write time rather than when
appending to output_bblocks. The premature shallow copy taken in d49f78a
was made before documentation and other fields were added to the live
metadata dict, so they were dropped from the output.
