Edit Dataset: Investigate and correct multiple draft issue.

[kcondon]

One user has two datasets that may have a published version mislabeled as draft in the version history.

Steps to reproduce:
In two separate browsers, open a published dataset.
In one browser edit metadata.
In the other browser, edit terms and add a guestbook.
Save the metadata view, then save the guestbook view.
See multiple drafts.

This has happened at least once in build. I haven't been able to recreate it locally. Kevin was unable to get it to happen on build. He thought it might be occurring in the presence of a long-running ingest, but even that wasn't enough to trigger a repeat.

Tried being logged in as different users - that didn't force multiple drafts.
Also tried saving in one window while a ingest was occurring in the original window. - that didn't do it either. Previously tried editing same and differing sections (metadata, files, terms.) - that didn't yield multiple versions.
