Investigate author setting on CMS DocDB

[ericvaandering]

Carrying over authors from one doc to an update is broken for CMS. It's broken at least as far back as 8.8.5, so need to check if this is a CMS only thing or if the problem is really with DocDB code

This seems to be a problem with the CMS javascript. Still investigating.

On FNALSSO version, I do not have to re-enter previously added authors
when I update metadata (including authors) using author search widget.

Yeah, I know. Once we get this release out I have to do a real search to figure out what the CMS problem is.
