Description Hugo Agud 2018-10-24 07:01:29 UTC
When merging two authotities if the two authorities  are in the same bibliographic record, at the end we have a duplicated subject.

Test plan:
1. Catalogue one record with two subjects from authorities
2. Merge authorities
3. check that the biblio now has a duplicated subject.
