Sample data should use its own UUID and title (not mirror a production record)

[jodygarnett]

It has been pointed out that loading the sample data may place a catalog in conflict with a harvested result (due to use of a real record as an example)

• Generate a unique UUID
• Update title to indicate "(Sample Data)"

(When this is fixed this issue can be closed)

The issue geonetwork/core-geonetwork#7274 has been closed. Instead of generating a unique UUID, it will instead ensure that the sample record does not overwrite any existing metadata with the same uuid.

The next step should be to update the existing sample data so that it indicates that it is sample data.
