Bug 32013: Autorenewal batch indexing

The automatic_renewals.pl cron script currently loops through items for automatic renewal and calls the indexer for each one individually. skip_record_index has now been added as a parameter to the AddRenewal function to skip the indexing process. The item numbers are now added to an array and then the indexer is called once from within automatic_renewals.pl and passed the array to queue one indexing job instead of multiple jobs.

Test plan:
1) AddRenewal uses Koha::Items->store() to trigger the indexing process. Run prove -vv t/db_dependent/Koha/SearchEngine/Indexer.t and check tests 5,6,29,30. These tests prove whether passing skip_record_index to store() triggers or skips the indexing process. All four tests should pass to show that skip_index_records can prevent the indexing being triggered.
2) Add multiple renewals that are able to be autorenewed and run the automatic_renewals.pl script. There should be multiple items queued in zebraqueue.
3) Apply patch and try again
4) There should now only be one job queued in zebraqueue
