EZID metadata registration doesn't seem to work with SIDs
Earlier today, a DOI was generated using R's `generateIdentifier` (which calls MNStorage.generateIdentifier()). Then the newly-minted DOI was set as the Series ID of an EML 2.1.1 Object. The DOI was successfully registered with EZID but the EZID metadata was not correctly set on the object, as shown when I logged in. See the attached screenshot.
I expected the EZID metadata to get filled in like it normally does for DOIs that get used as PIDs. I took a quick glance at the relevant part of Metacat and it doesn't look like anything special is done to handle SIDs.
