drivefs-uprev: Return UprevVersionedPackageResult instead of None

When drivefs attempts to uprev to the same version, the |uprev_result|
is returned as None. If the return from the PUpr handler is None, the
controller throws an error. The |UprevVersionedPackageResult| should be
returned to allow the property |uprevved| to return false (unless the
|add_result| method has been called, in which case it will return true.
