Fix DBpedia queries on CoyPu endpoint

[Perevalov]

What was done:

• Run all the queries on the endpoint https://skynet.coypu.org/dbpedia/
• Identify the failed ones
• Fix the failed ones
• Re-run all the queries to get the updated answers

Dear Aleksandr, I understand that due to the change from Virtuoso to Apache Fuseki, some queries (actually a lot) needed changes. The answers should not change that drastically since they will change benchmarking results. I am not sure that this is the right way to go. What do you think? It would also change QALD-10 train results, or?

The number of queries that were changed is 14 (train) and 24 (test). For ca. 50% of them, the answers were the same. However, as I also re-run all the queries over the new endpoint, many answers have changed also (some of them maybe just have a different order, but still it is reflected in the files).

As discussed let us create git tags for each version of the dataset
