The Antivirus application causes Attachment*Events to not be triggered #30
Description
Example side-effect: When deleting an attachment from a wiki page, the Solr search index is not updated and the file can still be found with search, even if you can not access it if you follow the search result.
Reported product issue: https://jira.xwiki.org/browse/XWIKI-18775
For Antivirus, we can apply the workaround mentioned in the product issue.
Tested on XWiki 12.10.6, but it could be causing issues as early as 11.3-rc-1, 10.11.7, if the root cause is indeed https://jira.xwiki.org/browse/XWIKI-15805.
