wrong icon appears for data in package from metacat
An icon appears in the first column of a result set that indicates whether or
not the data set contains data+metadata or just metadata. If you create a
package local with data and then synchronize to metacat, the icon indicates that
there is no date, although data is clearly displayed in the data table.
For some unknown reason, the information from metacat seems to indicate that
there is no data, even though it is apparently there. Test seems to be based on
presence of 'isDataFileFor' string in triples.
