Items without date.accessioned are perminantly sorted to the top of all date
based searches.

Key: DS-1052
URL: https://jira.duraspace.org/browse/DS-1052
Project: DSpace
Issue Type: Bug
Components: DSpace API
Reporter: Scott Phillips
Assignee: Scott Phillips
Priority: Major
Almost all items in DSpace have a dc.date.accessioned because it is
automatically assigned when the item is created. There are two conditions which
can occur that causes an item to get lose it's accessioned date.
1) A person with editing privileges on an item removes the dc.date.accessioned
metadata field.
2) The item's accessioned date is created via the InstallItem.restore() method.
When one of these conditions occur the item gets inserted into the browsing
sort table with a null value. When ever a recent submission query is run these
items will always be returned first because Postgres and Oracle always return
NULLS first when executing an ORDER BY clause. This means that these items are
permanently penned at the top of the RSS feed and recent submissions sections
sections.
