Deleted Attachments Returning in the Space Attacment List After a Content Index

Attachments which have been deleted from a Confluence Page are still searchable and viewed after a Content Index is performed.

Steps to Reproduce

1. Add an attachment to a Confluence Page (does not need to be embedded on the page itself)
2. Search for the Attachment using the Filename of the Attachment; it should display in the Search Results
3. Delete the Attachment
4. Search again for the Attachment; should not display in the Search Results
5. Move the page that used to contain the attachment, or
   • Perform a task which triggers a Content Index (Move Pages, Create Space, etc) or as SysAdmin, manually trigger a Content Re-Index

The attachment also reappear in the Space Attachment list by going to Space Tools > Content Tools > Attachments
