Remove the GUID requirement from the ContentId

Remove the GUID requirement from the ContentId

In Java persisting the ContentId required it to be a guid.  This removes
that dependency.  Note that legacy downloads still have their own checks
for requiring the id to be a guid, but if the download isn't associated
with a legacy download the checks should not occur.
