LinksUpdate and SMW 1.9

[1] describes an issue where LinksUpdate apparently no longer works with SMW 1.9. The provided MwLinksUpdateWithSQLStoreDBIntegrationTest proves otherwise (it is an integration tests between the Store and its database).

If LinksUpdate is executed manually together with an inappropriate use of Parse/Revision/ParserOutput then of course "doUpdate" will override existing data but as the test shows when used in suitable manner, data
from different revisions are updated correctly.
