dojson: handle obsolete ORCIDs

In rare cases an author may have 2 Orcid's. Although we'll try to get these cases solved on the Orccid side we should be prepared to deal with them. Currently they are put into 035__z. In the new schema Orcid's should be unique. A second Orcid should be automatically hidden.

Two interesting cases: https://inspirehep.net/record/1518989/export/xme and https://inspirehep.net/record/1005548/export/xme (both orderings appear in the data)

Another interesting case: https://inspirehep.net/record/1357501/export/xme (they also appear in the same field).

This probably requires something similar to #33.
