Bug 22690: (QA follow-up) Fix indexing for Items sets

This patch adds tests and handling for calling move_to_biblio on a
Koha::Items set that contains items from more than one source biblio.

Test plan
1/ Inspect the changes to t/db_dependent/Koha/SearchEngine/Indexer.t
2/ Run t/db_dependent/Koha/SearchEngine/Indexer.t and confirm it passes
