Some data on the demo content causes a failure in solr bundle indexing script.

• 101 - is not a complete object and the indexing fails cause of that (no attributes), removing al traces of this from the db manually seems to resolve it.
• Objects 102-104 do not have rows in ezcobj_state_link and that also makes the indexing fail.

Regardless of the consequences, demo data DB should be clean in order to prevent current and future issues.
