Some alternate PIDs from B2SHARE v1 are not pointing to the right URL

[nharraud]

Problem:
When records where migrated from b2share v1 to b2share v2 they were assigned an additional PID. The old one is kept as an alternate identifier in the record metadata. Some of those records' old PID are still pointing to the old B2SHARE v1 url.

Example:
For record https://b2share.eudat.eu/records/f54a1c6505e441909e4c54e0621a9284
The alternate identifier http://hdl.handle.net/11304/d836fea2-1f53-11e5-8a18-f31aa6f4d448 points to https://b2share.eudat.eu/record/240 instead of https://b2share.eudat.eu/records/f54a1c6505e441909e4c54e0621a9284
