Bug 26507: Elasticsearch - Index records after storing new item

Bug 26507: Elasticsearch - Index records after storing new item

Currently Item->store indexes the record before the DB update - that is wrong

To test:
 1 - Find/create a bib with no items
 2 - add an item with barcode "abc123"
 3 - do a general keyword search for "abc123," see your bib is not in the results
 4 - perform a search that includes your bib in the results, confirm it shows as having no items
 5 - click through to bib details, confirm it shows your item here
 6 - edit and save your item
 7 - confirm barcode is now searchable
 8 - apply patches
 9 - Add a new item "cde456"
10 - Confirm it returns in searches
11 - Edit 'cde456' and change barcode to 'fgh789'
12 - Confirm the new abrcode is searchable
