Non-rdf resources emit /fcr:metadata events instead of /jcr:content

Fixes https://www.pivotaltracker.com/story/show/81279166
@awoods Not exactly.  With an update on the binary, the event path is /path/to/resource/fcr:content -- I'm removing the /fcr:content to make the event path the resource path.  When the event is on the description, the path is already the resource path, so I'm leaving it unchanged.  So in both cases, the end result is that the event is emitted with the resource path.
