Test plan:

(A) Reproduce the bug:

A1 In Administration > System preferences > Web services:
   - Enable OAI-PMH
   - Enable OAI-PMH:AutoUpdateSets
   - Enable OAI-PMH:AutoUpdateSetsEmbedItemData

A2 In Tools > Export data > Export bibliographic records, export 1 (one)
   biblio record. Be sure that this biblio record has at least one item.
   Don't tick "Don't export items".

A3 Delete the exported biblio record, and its items.

A4 In command line, on the server load the exported file:
   ./bulkmarcimport.pl -b -v -file /path/to/koha.mrc
